Motion sensor/detector Infrared PIR - HC-SR501

Motion sensor/detector Infrared PIR - HC-SR501

Product information:

With this HC-SR501 sensor your Arduino can detect movement in a room!

When motion is detected you will get an adjustable time 3.3V high signal on the output. (Adjustable with VR1).
Then the HC-SR501's output goes low for 3 seconds to prevent double triggering.

Adjustable resistor VR1 determines how long the output goes high when motion is detected. Adjustable from +/- 5 seconds to +/- 300 seconds.
Adjustable resistor VR2 determines the detection distance (+/- 3-7m).
Jumper J1 determines whether the output goes low immediately after the first detection of motion or whether it waits until the motion has stopped.
In the H position it goes low again after the initial movement (although there is still movement).
In the L position it only goes low when no more movement is detected.

Detection angle: <140 degrees
Detection distance (adjustable): 3-7m
Delay (adjustable): 5-200s (default 5s +/- 3%)

Supply voltage: 4.5-20V
Current used: <60uA
Output voltage: high/low signal 3.3V TTL.
