HC-SR505 Mini Infrared PIR Motion Sensor Infrared Detector Module
- Wide operating voltage range: the default operating voltage DC4.5V-20V.
- Automatic induction: to enter the sensing range of the output is high, people leave the sensor range automatically delay off high, output low. Ultra-small size.
PIR Motion Sensor
PIR Motion Sensor Low-power consumption Output level: High 3.3V / Low 0V Trigger: repeatable trigger (default) Repeatable trigger: the sensor output high, the delay period, if there is human activity in its sensing range, the output will remain high until people leave after the high variable delay Low (automatically extended sensor module detects the human body after every activity a delay period, and the last time an event is the starting point of the delay time).
