Adafruit HC-SR501 PIR Motion Sensor Module - Green

Product Description

Adafruit HC-SR501 auto-senses light for various applications in house, basement, outdoor, warehouse, garage, etc. or for ventilator control, alarm, etc. It features automatic induction, When someone enters its induction range, it enter the high level and when people leave the sensor range is automatically delayed off high. After each sensing output (high level goes low), the sensing module can be followed by a blocking time, during which it is sensed The device does not receive any sense signals. This function can be used to achieve the interval between the sensing output time and the blocking time. It can be applied to the interval detection products. At the same time, this function can effectively suppress all kinds of interference in the process of load switching.
