1pcs HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module,HC-SR501 - cizihuu, 5Dba0db8OIT-0

• Output high-level signal: can be easily with various types of circuits to achieve docking. Automatic induction: When someone enters its induction range, enter the high level, people leave the sensor range is automatically delayed off high. Output low. non-repeatable trigger mode: the induction output high, the delay time is over, the output will automatically change from high to low. 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 the person will leave the high The level changes to low level (the sensing module automatically delays a delay time after every activity of the human body, and takes the time of the last activity as the starting point of the delay time)., Manufacturer: cizihuu
