DESCRIPTION

  • 2 Pieces HC-SR501 and brackets to suit.
  • Human Infrared IR Pyroelectric PIR Motion Sensor Detector.
  • It is great for microcontrollers such as arduino or funduino and many more including the rasberry pi!
  • With an operating voltage of 5v to 20v.
  • Operating voltage. High value of 3.3 volts and a low of 0 (it is either on or off). The delay time can be adjusted from 5 to 200 seconds as well as the sensing range from 3 to 7 meters. The entire sensor with the board is 32mm by 24mm (standard pir motion sensor). The sensor either gives off a 3.3 volt 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.
  • Working voltage range: DC 4.5-20V.
  • Static current: <50uA.
  • High level output: 3.3 V / low 0V.
  • Trigger mode: L unrepeatable trigger /H repeated trigger (Default Repeating trigger).
  • Delay time: 0.5-200S (adjustable) can be produced range 0.1 seconds - a few minutes.
  • Blocking time: 2.5S (the default) can be produced range 0.1 seconds, tens of seconds.
  • Size: 32mm*25mm circuit board.
  • Induction angle: <100 degree cone angle.
  • Working temperature: -15-+70 degrees.
  • Induction of lens size: diameter: 23mm (default).
  • NOTE: The white PIR Domes will be taken off for postage. You just push them back on easily.
