HC-SR501 PIR Sensor Module
HC-SR501 PIR Sensor Module
Specifications
- PIR IC sensor BISS0001
- Operating voltage range: DC 4.5-20V
- Level Output: High (3.3V) detected,
- Low (0 V) undetected
- Trigger: H / repeated trigger (default)
- Detection distance: 3-7 metres (Adjustable)
- Delay time : 5-200s (Adjustable)
- Blockade time 2.5 s (default)
- Board size: 3.2x2.4x2.5 cm
The Jumper / solder pads allows you to choose if the output should automatically reset itself after it is triggered.
If set to Auto-reset the sensor will stay high until the motion stops.
After motion is no longer detected the output will go low. If set to No reset the sensor will stop sensing once it has triggered, and stays high for the pre-set time period.
The potentiometer labelled Sensitivity allows you to select the distance that the sensor will work over. It can be varied from approximately 3m to 7m.
The potentiometer labelled Output timing adjusts how long the output is held high after the sensor is triggered. This can be varied from approximately 5 seconds to 300 seconds.
