- Microwave detection is a newer and more advanced occupancy sensor than the PIR– it works by emitting high-frequency electromagnetic waves and then receiving their echo. The sensor detects the change in echo from the slightest movement in the detection zone which commands a microprocessor to switch the light on.

To combat the PIRs temperature detection fault, Green Lighting developed a PIR sensor with Tri-Sensor Technology. The P-Lux LED Lantern Range, incorporates a sensor that combines a PIR with a thermometer, allowing the lantern to automatically adjust the PIRs sensitivity depending on the ambient temperature. This, combined with a photocell and ...
Microwave sensors can be more efficient for indoor lighting, this is because Microwave sensors are incredibly sensitive to movement, even being able to sense motion through thin walls, glass and plastic. If you’re using a microwave sensor as a security light, there’s a higher chance of false alarms. Don’t use them facing conservatories ...

In lighting applications, microwave sensors are a type of motion detector that switches a light on when the sensor detects movements. These sensors can react within less than 1/5 of a second. And more advanced models can even detect whether a person is moving towards or away from the sensor, or moving randomly.
We can provide a comprehensive list of Ansell fittings, along with their respective microwave sensor. These sensors have adjustable settings that can allow the end user/installer to alter the detection area and sensitivity, which will aid in reducing the frequency of false triggers in your lighting.
Jan 19, 2024 · The sensor incorporates circuitry to amplify and process these signals, specifically filtering out random disturbances and targeting human motion. When the predefined motion signature is detected, the PIR sensor promptly sends an activation signal to the lighting system, turning on the lights.
Passive infrared (PIR) and microwave (MW) sensors are both widely used in lighting control. They both have the ability to detect moving objects, such as human bodies, but they work in quite different ways to each other.
