ITEM NAME:New HC-501 Infrared PIR Motion Sensor Module for Arduino Raspberry OS Description: It is great for microcontrollers such as arduino for funduino and many more including the rasberry pi! It is a HC--SR501 Sensor Module with an operating voltage of 5v to 20v. Operating voltage. It has a high value of 3.3 volts and a low of 0 (it is either on or off). It's delay time can be adjusted from 5 to 200seconds as well as the sensing range from 3meter to 7meters. The entire sensor with the board is 32mm by 24mm (standard pir motion sensor). The sensor either gives off a 3.3volt high value when motion is detected and then resumes or continues to give off a 0 voltage when no motion is detected. If you use an arduino or other micro controllers you can use the 3.3 volt out to power the sensor or use the 5 volt power pin (vcc) to power the sensor. Either one will work. Specification： Working voltage range: DC 4.8-20V Static current:
