Mini PIR Motion Detector


Availability: Low Stock - Only 1 Remaining


SKU: SEN-073 Mfg Part Number: HC-SR505 Category: Tags: , ,


A PIR motion sensor is a type of motion sensor that passively monitors infrared light in its field of view. When the sensor sees a change in the level of infrared light, it interprets this as motion. These sensors are commonly found in in a variety of common products – from Alarm Systems and Outdoor Security Lighting to those fancy Room Occupancy Sensing Light Switches.

This is the smallest PIR sensor we carry – the sensor element itself measures just 10mm in diameter and 10mm in depth, with the total length including the PCB measuring 34mm. Motion can be detected at a range of up to 3 meters with a 100 degree field of view.

Input voltage is wide ranging – it will take anywhere between 4.5 an 20VDC while the output is both 3.3V and 5V logic save. When motion is detected, it will pull the output pin high.



  • Input voltage: 4.5 – 20VDC
  • Delay time: 8S +/-30%
  • Detection range: 3 Meters
  • Static current: under 60uA
  • Total Length: 34mm
  • Output: 3.3V High / 0.0V Low
  • Field of view: 100°
  • Working temperature: -20° – +80°
  • Sensor Diameter: 10mm
  • Sensor Length: 10mm

    Max distance from Raspberry Pi2? Planning about 25 feet? Have a box of Cat5e?

    I am guessing maybe a plastic sleeve might me nice to protect the board. Plan on having it stick out of the wall just showing the plastic end.

  2. Chris @ BCR

    Maximum distance for a low power / low data rate sensor is going to be quite far – 25′ wouldn’t be a problem. The plastic sleeve would be a good idea.

    Cable can be custom ordered, we do have up to 15′ CAT6 in stock.
