PIR Motion Sensor Module for Arduino

This fully assembled PIR movement sensor detector module offers a number of useful features including adjustable sensitivity and adjustable on-time duration from 3 to 200 seconds. It is ideal for use with Arduino and similar systems.

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 ).

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.
