PIR infrared sensor module is based on infrared technology, automatic control products. High sensitivity, high reliability, low power consumption, low voltage operation mode. Widely used in various auto-sensing electrical equipment, especially for battery-powered automatic control products.It’s Compatible with ARDUINO, RASPBERRY PI, AVR, PIC, 8051, etc.It has automatic induction to enter the sensing range of the output is high, people leave the sensing range is automatically delay off high, output low.
The photosensitive control can be set photosensitive control, day or light intensity without induction.
There are two kinds of trigger modes-Unrepeatable Trigger in which the sensor output is high, the delay time is over, the output automatically from high into low.The second is Repeatable Trigger in which the sensor output is high, the delay period, if there is human in its sensing range Activities, the output will remain high until the delay will leave high to low .
