An Adjustable PIR Motion Sensor is an intelligent lighting controller that automatically switches connected lights ON when movement is detected and turns them OFF after a configurable delay. Unlike basic motion sensors, adjustable PIR sensors allow users to customize detection range, delay time and ambient light (LUX) settings, making them suitable for a wide range of residential and commercial lighting applications.
Esysense offers a range of adjustable PIR motion sensors for wall-mounted, ceiling-mounted and compact recessed installations, helping users achieve greater convenience, improved safety and significant energy savings.

What is an Adjustable PIR Motion Sensor?
A Passive Infrared (PIR) sensor detects the heat emitted by moving people. Unlike conventional switches, it operates lighting automatically.
When someone enters the detection area:
1. Motion is detected.
2. The connected light switches ON.
3. A timer starts automatically.
After movement stops:
1. The preset delay expires.
2. The light switches OFF automatically.
The adjustable controls allow the sensor to be configured according to the installation environment.
Bottom Line:
Adjustable PIR motion sensors provide greater flexibility than standard motion detectors, making them suitable for many different indoor applications.
Adjustable Settings Explained
Detection Range:
Allows installers to optimize how far the sensor detects movement.
Delay Time:
Controls how long the light remains ON after the last detected movement.
Common delay settings include:
1. Short delay for corridors
2. Medium delay for washrooms
3. Longer delay for offices or meeting rooms
Ambient Light (LUX):
Determines when the sensor becomes active.
Users can choose:
1. Night-only operation
2. Day and night operation
3. Custom light threshold
These adjustments improve both user comfort and energy efficiency.
Benefits of Adjustable PIR Motion Sensors
Compared with fixed sensors, adjustable models provide:
1. Better lighting control
2. Reduced false triggering
3. Lower electricity consumption
4. Longer LED lifespan
5. Greater installation flexibility
6. Improved user comfort
Because the settings can be customized, one sensor can suit multiple environments.
Best Applications
1. Homes: Automates lighting in hallways, kitchens and entrances.
2. Offices: Reduces unnecessary lighting in meeting rooms and workspaces.
3. Corridors: Ensures lights remain ON only while people are present.
4. Washrooms: Provides touch-free lighting for improved hygiene.
5. Staircases: Improves safety while reducing energy consumption.
6. Storage Rooms: Automatically illuminates low-traffic areas when required.
Bottom Line:
Adjustable PIR sensors are suitable wherever occupancy-based lighting control is needed.
