What Is a PIR Motion Detector and How Does It Work?
PIR stands for passive infrared. Unlike active sensors, a PIR motion detector does not send out a signal of its own. Instead, it watches for changes in the infrared energy inside its field of view. A person who walks across that area changes the energy pattern, so the sensor reacts to it.
Because of this principle, a PIR sensor suits occupancy-based lighting, where lights stay on only while people are present. It also works as the detection element in security setups. The terms PIR motion sensor, PIR motion detector and PIR sensor describe the same basic technology. However, product designs varies by mounting style, coverage angle and application, so you should choose a model with those factors in mind according to your application.
Browse Sensors by Mounting Style
Ceiling-Mounted 360°
Ceiling sensors watch the area below them in every direction. As a result, they suit rooms where people enter from several sides. The 1L-PS01 Ceiling Mount PIR Sensor 360° provides 6 m detection range for ceiling heights from 2.2 m to 4 m. It suits offices, classrooms, corridors, restrooms and parking areas. The 1L-PS012 Ceiling PIR Sensor 360° also mounts on the ceiling and serves general occupancy-based lighting. For its range and height limits, check the product page or you can also ask our team to suggest you according to your layout.
False-Ceiling 360°
The 1L-PS02 False Ceiling Mount PIR Sensor 360° sits recessed in a false ceiling. Therefore, it keeps the ceiling surface neat in finished interiors. It provides 360° coverage with a 6 m detection range and works at mounting heights from 2.5 m to 3.5 m. Hotels, showrooms, retail spaces and modern interiors are its listed applications. Choose this model when the ceiling finish matters to your project.
Wall-Mounted 180°
The 1L-PS10 Wall Mount Motion Sensor 180° faces one direction and covers a 180° area with a 12 m detection range. You mount it at heights between 1.8 m and 2.5 m. Corridors, staircases, lobbies, garages and balconies suit this layout, because people move along a clear path in front of the sensor. In narrow spaces like these, a forward-facing sensor often matches the layout better than an all-round one.
Weatherproof 180° Model for Outdoor Use
The 1L-PS08 Weather Proof PIR Sensor 180° carries an IP65 rating and provides 180° coverage with a 12 m detection range. Its mounting height range runs from 1.8 m to 2.5 m. Outdoor entrances, driveways, gardens, boundary walls and parking areas count among its applications. Because only this model carries an IP65 rating, select it for exposed positions. For any other outdoor requirement, please contact us first.
Pet-Immune Motion Detector for Security
The LC-200 PIR Detector with Pet Immunity targets security use. It reaches 15 m with a 100° field of view, and it ignores pets up to 15 kg. In addition, it runs on 13.8 Vdc and supports tamper and EOL connections. Homes, villas and small shops make up its listed applications. Before you buy, confirm that your alarm panel matches these electrical details.
How to Choose the Right Passive Infrared Motion Sensor
Work through these five steps to narrow down your options.
- Measure your mounting height. Start with the height of the ceiling or wall. The 1L-PS01 works from 2.2 m to 4 m, while the 1L-PS02 works from 2.5 m to 3.5 m. Wall and weatherproof models work from 1.8 m to 2.5 m. If your height falls outside these ranges, talk to us before you order.
- Choose the coverage pattern. Next, decide how much area you need to cover. A 360° sensor watches the space around it, so it suits open rooms. A 180° sensor faces forward, which suits corridors and entrances. The LC-200 uses a 100° field of view for security detection.
- Match the environment. Then consider where you will install the sensor. Indoor spaces open up the ceiling, false-ceiling and wall models. Outdoor positions point toward the IP65 1L-PS08.
- Define the purpose. After that, decide what the sensor must do. Occupancy-based lighting calls for the ceiling and wall sensors. Intrusion detection in a home with pets calls for the LC-200.
- Confirm the electrical details. Finally, check supply voltage, output type and load rating against your control panel or lighting circuit. Send us your requirements, and we will help you verify them.
Where These Sensors Are Used By Buyers
- Offices, classrooms and restrooms. These spaces need lights that follow occupancy. The 1L-PS01 gives 360° coverage from the ceiling for such areas. Likewise, the L-PS012 supports general occupancy-based lighting.
- Hotels, showrooms and retail. Appearance matters as much as function in these interiors. Accordingly, the recessed 1L-PS02 fits into the false ceiling.
- Corridors, staircases, lobbies, garages and balconies. People travel along set routes here. The 1L-PS10 covers 180° at up to 12 m, which suits these walkways.
- Outdoor entrances, driveways, gardens and boundary walls. Exposed positions call for a weatherproof rating. The IP65 1L-PS08 serves these locations, and it also works in parking areas.
- Homes, villas and small shops. Security setups in these buildings often need pet tolerance. The LC-200 supports this need for pets up to 15 kg.
Using Sensors for Occupancy-Based Lighting
Occupancy-based lighting switches lights according to presence in a space. When people leave, the lights can turn off, so rooms do not stay lit without a reason. This approach supports energy-efficient lighting control in offices, schools, hotels and commercial buildings. Ceiling sensors suit open rooms, whereas wall sensors suit walkways.
Large projects often need more than one model. For example, a commercial building can use the 1L-PS01 in offices and the 1L-PS10 in corridors. Meanwhile, the 1L-PS08 can protect the outdoor entrance and parking area. Because all of these models come from one range, you can plan the whole site with a single supplier. Send us your floor plan details, and we will help you match each zone to a suitable model.
Technical Points to Check Before You Order
- Mounting height. Install each sensor within its listed height range so that you match the specified coverage.
- Range versus angle. Detection range tells you how far a sensor reaches, whereas coverage angle tells you how wide it looks. Compare both values on the product page.
- Weather rating. Only the 1L-PS08 lists an IP65 rating. Do not assume that other models suit outdoor installation.
- Pet weight. The LC-200 ignores pets up to 15 kg. Therefore, check your pets’ weight against this limit
- Security wiring. The LC-200 runs on 13.8 Vdc and supports tamper and EOL connections. Confirm compatibility with your alarm panel.
- Electrical details. Supply voltage, output type and load rating vary by project. Ask us if you cannot find them on a product page.
Where 1 LEAP PassiveIR Motion Sensors Are in Use
Over the years, 1 LEAP Technologies has supplied PIR motion sensors across retail, e-commerce, food service, transport and infrastructure. Reliance, for instance, buys our sensors in bulk quantities, so large-volume orders are part of how we work.
In e-commerce and warehousing, we have supplied sensors to Amazon, Amazon Warehouse, Flipkart and ShopClues. Food and beverage businesses make up an another group, including KFC, Domino’s, Dhaba by Claridges, Aban Beverages Pvt. Ltd. and Burger Farm Pvt. Ltd. Meanwhile, public transport and infrastructure buyers such as Indian Railways, Delhi Metro and BuildMyInfra have also received our sensors in bulk quantity.
This mix of buyers shows the range of spaces our sensors serve, from stores and warehouses to restaurants and stations.
These organisations run large and busy spaces, such as warehouses, restaurants, stations and offices. Lights in such spaces can stay on even when nobody is present. A PIR sensor switches the lights off when the area is empty, and it switches them back on when someone enters in the room. Therefore, sites with many lights and long operating hours stand to gain the most from occupancy-based control.
Savings Example: Lighting Load With and Without Sensor
The example below shows how a PIR sensor can lower your lighting energy use on a commercial meter. It assumes a connected lighting load of 200 W, an electricity cost of ₹10 per unit and a 30-day month. It also assumes that the sensor cuts the daily operating hours from 12 to 6.
Parameter | Without PIR sensor | With 1 LEAP PIR sensor |
|---|---|---|
Connected lighting load | 200 W | 200 W |
Operating hours per day | 12 | 6 |
Energy used per day | 2,400 W/h | 1,200 W/h |
Days in a month | 30 | 30 |
Energy used per month | 72 kWh | 36 kWh |
Electricity cost per unit | ₹10 | ₹10 |
Monthly electricity cost | ₹720 | ₹360 |
Monthly saving | – | ₹360 (50%) |
In this example, the sensor halves the hours that the lights stay on, so the monthly cost falls from ₹720 to ₹360. However, your own result depends on how long people actually use the space. Moreover, a higher connected load saves more rupees, because the same reduction in hours applies to more power.
