HC-SR501 Adjust IR Pyroelectric Infrared PIR Human Infrared Motion Sensor Detector Module for Arduino for Raspberry Pi

説明

The human infrared sensing module is an automatic control product based on infrared technology. Widely used in automatic induction electrical equipment, suitable for automatic control products powered by dry batteries.

製品の特徴：

1. Two triggering methods: L cannot be repeated, H can be repeated. Jumper selection is available, default is H.

A、 Non repeatable triggering method: After sensing the output high level, once the delay time ends, the output will automatically change from high level to low level.

B、 Repeatable triggering method: that is, after sensing the output of a high level, during the delay period, if a human body is active within its sensing range, its output will remain high until the person leaves, and then the delay will change the high level to low level (the sensing module will automatically extend a delay period after detecting each human body activity, and the time of the next activity will be the starting point of the delay time)

2. Light sensitive control: The module has reserved space for setting light sensitive control, which does not sense during the day or in strong light.

3. Induction output blocking: The induction module can set a blocking time immediately after each induction output (from high level to low level), during which the sensor does not receive any induction signals. This function can achieve interval operation between sensing output time and blocking time, and can be applied to interval detection products; At the same time, this function can effectively suppress various interferences generated during the load switching process.
