AS312 PIR SENSOR MODULE FOR ESP32/ESP8266
This is a PIR sensor module that supports ESP32 and ESP8266 IOT development boards. These Mini Passive Infrared Sensors work exactly like their bigger brothers, however they take about a fifth to half the size compared to its counterpart! PIR sensors are pyroelectric, meaning that when a motion is detected from the change in the infrared levels it will report active high signal to indicate presence of movement. When there is no movement it will be active low offering a 0v signal to indicate there is no movement near it. Once the unit is triggered you must wait 8 seconds for it to reset. For detailed working principle, go to the following link. I also attached AS312 sensor data sheet.
