The pir motion sensor detector module hc-sr501 allows you to sense motion. It is almost always used to detect the motion of a human body within the sensor's range. It is often referred to used "Pir", "Pyroelectric", "Passive infrared" and "Ir motion" sensor. The module has an onboard pyroelectric sensor, conditioning circuitry, and a dome-shaped fresnel lens. It has a delay time adjustment potentiometer and sensitivity adjustment potentiometer. Repeat trigger selection jumper is also available. Compatible with arduino, raspberry pi, avr, pic, 8051, etc. Specifications: wide working voltage range: dc 4.5v- 20v current drain: detection angle: detection distance: 3 to 7m (can be adjusted) blockade time: 2.5s (default) work temperature: -20-+80°c application: automatically sensing light for floor, bathroom, basement, porch, warehouse, garage, etc. Package includes: 5 x pir motion sensor detector module hc-sr501
