Hc-Sr501 Small PIR Sensor Module; Infrared Body/Motion Sensor

HC-SR501 PIR Motion Sensor Module GreenFeaturesAn easy-to-use PIR sensor module with a single digital output.
A 3.3V signal is output when motion is detected and is latched for an adjustable period of time. The output is then latched low for about 3s to avoid accidental re-triggering.
VR1 controls the length of the latched high output when motion is detected. It can be varied from about 5s (default) to about 300s.
VR2 controls the center of the detectable distance and can be varied from about 3m to about 7m.
With the jumper set to the 'H' position (default), sensing is disabled after a sense event (ie. once output is high).
With the jumper set to the 'L' position, sensing is enabled after a sense event. This allows for continuous motion detection. The output is still latched low for 3s once motion is no longer detected.
There is an unpopulated position on the PCB for an LDR (photoresistor).
