Motion Sensor Lighting
What Is Motion Sensor Lighting?
Motion sensor lighting covers the sensor technology — typically a PIR (passive infrared) sensor — that automatically triggers a light based on detected movement. It's the control method, distinct from the fixture itself (covered on our Flood Light Installation page) and from the broader security purpose it often serves (covered on our Security Lighting page). Getting the real value out of a motion sensor comes down to understanding how it actually detects movement, not just picking a product off a shelf.
Bright Right Electric installs and calibrates motion sensor lighting for homeowners across Sonoma County, as a CSLB-licensed electrical contractor (#1156335) based right in Rohnert Park.
Motion Sensor Lighting
Our Process
A motion sensor lighting installation moves through the same core stages:
01
Use-Case Assessment
We talk through where and why you want motion-activated lighting — entryway security, indoor convenience, or both.
02
Sensor Type Selection
We recommend PIR, dual-technology, or a combination based on your specific location and false-trigger risks.
03
Placement & Mounting
We mount and aim the sensor correctly, accounting for the real detection pattern, not just a standard height.
04
Sensitivity Calibration
We adjust sensitivity and timer settings to match your specific environment.
05
Testing
We test the sensor under real conditions, day and night, to confirm it performs as expected.
06
Walkthrough
We show you how to adjust settings yourself if your needs change.
Motion Sensor Lighting
How Much Does Motion Sensor Lighting Cost?
Cost depends on whether you're installing an indoor switch on existing wiring, an outdoor fixture with an integrated sensor, or upgrading an existing setup — an indoor switch swap is generally the most affordable option, while a new outdoor circuit costs more.
Motion Sensor Lighting
How a Motion Sensor Actually Detects You
Most residential motion sensors use PIR (passive infrared) technology, which detects changes in infrared radiation — essentially body heat — as it moves across the sensor's field of view. This detail matters more than most people realize: PIR sensors detect movement crossing their field of view far more reliably than movement heading straight toward them. A sensor aimed directly down a walkway will miss someone walking straight at it until they're quite close.
Why Your Motion Light Has a "Short Range"
This is the single most common complaint, and it's usually not what people think: the real fix isn't cranking up the sensitivity, it's re-aiming the sensor so approaching movement crosses its field of view instead of heading straight at it. Combined with the right mounting height — commonly 6 to 10 feet, angled slightly downward — this solves most "weak" motion sensor complaints without touching a single setting.
Real Causes of False Triggers
A motion light that keeps turning on for no reason usually has a real, diagnosable cause:
- Nearby heat sources — an AC exhaust vent, dryer vent, or chimney can register as movement, since PIR sensors are highly sensitive to sudden temperature changes.
- Small animals — pets or wildlife at ground level are a common trigger, especially with a sensor mounted too low.
- Swaying vegetation — bushes or tree branches moving in the wind can register as motion.
- A dirty or cobweb-covered lens — spiders are drawn to the warmth near sensors, and a web across the lens is a surprisingly common, easily-missed cause of constant false triggers.
Mounting at least 7 feet high specifically helps reduce pet-triggered false alarms, and repositioning away from heat sources and vegetation resolves most of the rest.
Motion Sensor Lighting
LowSensitivity and Range: What the Numbers Actually Mean
Sensitivity settings directly affect detection range:
| Sensitivity | Typical Range | Best For |
|---|---|---|
| Low | ~3–5 meters (10–16 ft) | Close-range areas, reducing pet/animal triggers |
| High | ~8–12 meters (26–39 ft) | Longer approach areas like drivewa |
*At the higher end, sensors can detect thermal changes as small as 0.1–0.3°C — genuinely precise, but also more prone to false triggers from minor environmental changes.
Motion Sensor Lighting
PIR vs. Microwave vs. Dual-Technology Sensors
Most residential sensors are PIR, but it's worth knowing the real alternatives:
- PIR (passive infrared) — detects body heat, needs a clear line of sight, the standard residential choice.
- Microwave — emits waves and measures reflection changes, can detect through some thin materials.
- Dual-technology — combines both for higher accuracy and fewer false triggers, at a higher cost.
Indoor Uses Beyond Security
Motion sensor lighting isn't just for driveways and entryways — a motion sensor switch is a genuinely convenient upgrade for closets, pantries, hallways, bathrooms, and garages, where hands-free lighting is simply practical, not security-driven.
Keeping Your Sensor Accurate: Simple Maintenance
A gentle wipe of the lens with a soft, slightly damp cloth (no abrasives) and clearing away cobwebs or debris seasonally keeps a sensor performing accurately — a dirty or obstructed lens reduces both range and reliability. Sensors showing consistent detection failures or excessive false alarms after 5 to 7 years of service are often simply due for replacement.

What Rohnert Park Customers Are Saying
"This is the most professional company I have ever worked with. I am a difficult person and hard to please (I have really high standards (as a retired science teacher) and I am skeptical of workmen and I'm a perfectionist!). Bright Right is currently working on the 3rd job I have hired them for – everything has gone smoothly, no stress at all!!! They are so friendly and so courteous. Rick and Dustin are an effective team with their two unique personalities – both very upbeat, serious, and kind. They explain everything in detail and answer all my questions (I am hyper-concerned about my property), and they are basically experienced, conscientious electricians you can trust."
— Nora Parker · Google Review
"I recently hired Dustin for some electrical work at my home, and I couldn't be happier with the results. He installed a high-quality bathroom fan, finished installing several outlets around the house, and completed a new electrical panel installation. From start to finish, Dustin was professional, knowledgeable, and clearly takes pride in doing the job right. The new panel installation was the bigger job, and Dustin handled it with real expertise. Everything was organized, labeled, and done to a very high standard, which gave me a lot of confidence in the safety and quality of the work."

Questions
Frequently Asked Questions
How does a motion sensor light work?
Most residential motion sensor lights use a PIR (passive infrared) sensor, which detects changes in infrared radiation — typically body heat — as it moves across the sensor's field of view, triggering the light to turn on.
How high should a motion sensor light be mounted?
A commonly recommended height for general-purpose residential PIR sensors is 6 to 10 feet, angled slightly downward. Mounting at least 7 feet high specifically helps reduce false triggers from pets.
Why does my motion sensor light keep going off for no reason?
Common causes include nearby heat sources like an AC or dryer vent, small animals, swaying vegetation, and direct sunlight. Adjusting sensitivity and repositioning away from these sources typically resolves it.
How do I stop my pet from triggering my motion sensor light?
Mounting the sensor at least 7 feet high and lowering sensitivity both help, though proper placement matters more than sensitivity alone.
What is the detection range of a motion sensor light?
It depends on sensitivity. Low sensitivity typically covers roughly 3 to 5 meters, while high sensitivity can extend to roughly 8 to 12 meters, detecting even small thermal changes.
PIR vs. microwave motion sensor — what's the difference?
PIR sensors detect body heat and need a clear line of sight — the standard residential choice. Microwave sensors emit waves and can detect through some thin materials. Dual-technology sensors combine both for higher accuracy.
Can motion sensor lights be used indoors?
Yes. Motion sensor switches work well for hands-free lighting in closets, pantries, hallways, bathrooms, and garages, not just exterior security applications.
How do I adjust the sensitivity on my motion sensor light?
Most sensors have a dial labeled "Sens" or "Range." Turning it toward the lower setting raises the threshold of heat change required to trigger, reducing false positives from animals or moving plants.
Why does my motion light have a short detection range?
This is often an aiming issue, not a sensitivity issue — PIR sensors detect movement crossing their field of view far better than movement heading straight at them, so a sensor aimed directly down a path should be re-angled.
How often should a motion sensor light be cleaned or maintained?
Periodically, especially outdoor units — a soft, damp cloth (no abrasives) removes dirt, and clearing away cobwebs seasonally prevents webs across the lens from causing false triggers.

Electrical Panel Upgrades in Rohnert Park
Replacing an undersized or obsolete panel is the most common job we perform in Rohnert Park, and it's the one that unlocks everything else. If your home still runs original 100-amp service, a Federal Pacific Stab-Lok, or a Zinsco panel, you're working with equipment engineered for a much smaller electrical load — and, in the case of those two brands, with a documented history of breakers that fail to trip. Upgrading to 200-amp service makes EV charging, battery backup, heat pumps, and modern appliance loads possible without constantly tripping breakers. We size the new service to what your household actually needs, pull the permit, coordinate the PG&E disconnect and reconnect, and meet the inspector for final sign-off.
EV Charger Installation in Sonoma County
Bright Right installs Level 2 home charging sized to your vehicle and, just as importantly, to your panel's actual available capacity. We run the dedicated 240-volt circuit, mount and commission the charger, and handle the permit — installing Tesla Wall Connectors, universal J1772 and NACS units, and hardwired or plug-in setups across Rohnert Park, Petaluma, and Santa Rosa. The detail most homeowners don't hear until it's too late is that many Sonoma County panels can't support a Level 2 charger without a service upgrade first, so we run a load calculation before you buy equipment, not after. We can also pre-wire a second circuit if a second EV is anywhere in your future.
Standby Generators & Backup Power
Public safety power shutoffs are a fact of life in Sonoma County, and so are winter storms that take lines down in the hills. We install whole-house standby generators with automatic transfer switches that pick up the house within seconds of an outage, wire inlets and manual transfer switches for portable generators, and add whole-house surge protection so your equipment isn't damaged when the utility comes back online. We'll also tell you honestly which tier makes sense — not every home in Cotati or Penngrove needs a whole-house unit when a critical-loads panel that keeps the refrigerator, well pump, internet, and a few circuits alive costs a fraction as much.
Solar & Battery Systems
We handle new photovoltaic installation, battery storage, system additions, and remove-and-replace work when a roof needs attention or a system has failed — plus service on existing arrays that aren't producing what they should. If you inherited a solar system with the house and nobody can tell you how it's wired or whether it's still under warranty, we can assess it and give you a clear picture. Battery storage in particular has changed the math for Sonoma County homeowners: between shifting utility rate structures under NEM 3.0 and the frequency of outages, a battery paired with existing solar is often a better investment than adding more panels.
Interior & Exterior Lighting
Recessed and can lighting, full LED retrofits, under-cabinet lighting, dimmer and smart-switch installation, fixture and chandelier hanging, landscape lighting, and security and motion-sensor lighting for homes across Rohnert Park and the University District. On the commercial side we handle lighting retrofits for offices, retail spaces, and warehouses along the Commerce Boulevard corridor, including the fixture and control changes that come with California Title 24 compliance. Lighting is one of the few electrical upgrades where the difference is immediately visible, and it's frequently the cheapest way to make a dated room feel finished.
Electrical Troubleshooting & Repair
Breakers that trip for no obvious reason, circuits that go dead, lights that flicker when the dryer starts, outlets that no longer hold a plug, GFCIs that won't reset, a faint burning smell you can't locate. These are the calls where experience shows. We trace a fault to its real source instead of swapping parts and billing for guesses, which is why our repairs hold and why we get called in behind other contractors who couldn't find the problem. In older Sonoma County homes the cause is often a failing backstab connection, a corroded neutral, a rodent-damaged run in a crawlspace, or a decades-old junction box buried behind drywall.
Custom Homes & New Construction
Full electrical for ground-up residential builds, major remodels, and additions throughout Sonoma, Marin, and Napa County — load calculations and plan review, service and meter setup, rough-in, trim, and final inspection. We work with general contractors, designers, and owner-builders, and we're comfortable on high-end custom projects near Sonoma State University where the lighting design, low-voltage layout, and smart controls all have to be coordinated before a single wire goes in. Getting the details right at rough-in is what keeps a home safe and functional for the next forty years — and it's far cheaper than fixing it after the drywall is up.
Commercial Electrical & Tenant Improvement
Service upgrades, panel and subpanel work, dedicated circuits for equipment, lighting retrofits, EV charging for employee and customer parking, and full tenant-improvement electrical for offices, retail, restaurants, and light industrial space along Redwood Drive and beyond. We understand a commercial job runs on someone else's schedule, so we work around business hours when the scope requires it. From a single dedicated circuit to a complete build-out, you get one licensed contractor coordinating permits, PG&E, and inspection — with clear pricing and a clean, code-compliant result.
