DescriptionThe PIR HC-SR501 Sensor is a pyroelectric device that detects motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can be detected by checking for a high signal on a single I/O pin.Features:Single bit outputSmall size makes it easy to concealCompatible with all microcontrollersTTL outputDelay time: 5 – 200 secondsSensing Range: about 120°, 7metres maximum.Adjustment:Rotating the SENSITIVITY ADJUST potentiometer in clockwise direction increases the sensing distance. Rotating in anticlockwise direction decreases sensing distance.Rotating the TIME DELAY AJUST potentiometer in clockwise direction increases the time duration for each HIGH pulse. Rotating in anticlockwise direction decreases the time duration.
