HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module for arduino for raspberry pi kits + Case

  This is its living application    Features:   1. Automatic induction: When someone enters its induction range, enter the high level, people leave the sensor range is automatically delayed off high. Output low. 2. photosensitive control (optional): the module reserved for location, can be set to photosensitive control, strong light during the day or not induction. Photosensitive control is optional, the factory did not install photosensitive resistor. If necessary, please buy a separate photosensitive resistor to install.   3. Two trigger modes: L is not repeatable, H is repeatable. Can be jumper selected, the default is H.     A. non-repeatable trigger mode: the induction output high, the delay time is over, the output will automatically change from high to low.     B. Repeated trigger mode: that is, after sensing the output high, in the delay time period, if the human body in its sensing range of activities, its output will remain high until the delay after
