PIR Motion Sensor Module Security Infra-red

HC-SR501 Pyroelectric Infrared Motion Sensor

A handy small device used for detectiing movement in alarms or robotics A good additionl for PICAXE and Arduino, other development systems.

Has on board pots for adjustment of detection range and output time.

Sensitivity Setting: turn to right, distance increases (approx 7M); turn to left, distance decreases (approx 3M)
Time Setting: turn to right, time increases (approx 300S); turn to left, time decreases (approx 5S).

Just hook up power and monitor the output line with your Arduino or Picaxe
