PIR Motion Sensor Detector Module, 5-20V

This fully assembled PIR movement sensor detector module offers a number of useful features including adjustable sensitivity and adjustable on-time duration. It offers two operating modes:

1. Non-retriggerable Mode (L): When triggered, the output goes high and will turn off after the on-time period has elapsed even if the sensor is still detecting movement. A factory set early retrigger prevention delay of about 5 seconds must pass before movement can retrigger the output
2. Retriggerable Mode (H): When triggered, the output goes high and will remain high after the on-time period has elapsed if the sensor is still detecting movement. The output will remain on until no movement is detected during the delay countdown

On-time is adjustable from 5-300 seconds.

The board has pads to connect additional components not supplied as standard:

• Position marked RT: designed to accept a thermistor for automatic temperature compensation
• Position marked RL: designed to accept a photoresistor or LDR to stop output activating during the day or when light is bright (Order Code QMA814-RL).

The sensor uses passive infrared (PIR) technology. If offers high sensitivity, ultra-low voltage mode and high reliability. It is ideal for use in security products, alarm systems, lighting control, industrial automation, toys, etc.

To control higher loads, the output can be used to drive the input of our 3044 Logic Activated Relay Board (select the version that matches the supply voltage used to power the PIR).
