PIR Motion Sensor - Front View
PIR Motion Sensor - Rear View PIR Motion Sensor - Side View Requires 3 x AAA Batteries Mini USB Socket to download MP3 sound files. Ideal for Point of Sale Displays


PIR Motion Sensors. Upload your own speech, music or sound effects. Our PIR Motion Sensors have a unique MP3 file download feature. Use the built-in Mini USB Socket to transfer an MP3 sound file directly onto the internal memory. Your MP3 file will playback automatically after the PIR sensor has been activated.

APPLICATIONS: Create an audible warning for a restricted area. Play an audible reminder or procedure to assist people with Dementia. "Remember to lock the door" or "Remember to close the windows and take your door key with you". Audible security alarms. Create a special door entrance greeting.

  • Upload an MP3 sound file with speech, music or any sound effect
  • Update and change your message as many times as you wish
  • Automatic audio playback after the PIR sensor has been activated
  • High quality MP3 sound output
  • One single MP3 file playback only, not multiple looped tracks
  • Wall mounting hole on rear side
  • Mini USB Cable included
  • Power Source: 3 x AA Batteries, (not included)
  • Mini USB Socket for direct downloading of MP3 files from your Computer
  • Audio playback format: MP3 format only
  • Sensor activation distance: Up to 4 metres with a 120 Deg Angle
  • Size: 90 x 60 x 25mm
  • Internal Memory: 16Mb, (Approx. 2MB)
  • Recording time: 2 minutes, (calculated at 128Kbps MONO bitrate)
  • Note: Recording time can be doubled to 4 minutes by changing the MP3 file sample bitrate to 64kbps. (See notes below)
  • Battery Life: 70 hours, i.e. 4,200 minutes, (252,000 seconds)
  • Number of playbacks: Based on the battery life calculations above, (using 3xAA 2,850mAh Batteries), a 10 second message will playback 25,200 times.

    This PIR Motion Sensor will only play one single MP3 file, NOT multiple tracks.

    What is PIR?
    PIR stands for Passive Infrared. A PIR Sensor is an electronic sensor that measures infrared light radiating from objects in its field of view. All objects with a temperature above zero emit heat energy in the form of radiation. Usually this radiation is invisible to the human eye because it radiates at infrared wavelengths, but it can be detected by PIR Sensors. PIR sensors don't detect or measure heat, but instead they detect the Infrared radiation emitted from an object. A PIR-based motion detector is used to sense movement of people, animals, or other objects. They are more commonly used in burglar alarms and automatically-activated lighting systems.

    What is the difference between normal Motion Sensors and PIR Sensors?

    PIR Sensors do not detect motion, instead they detect abrupt changes in temperature at a given point using the Infrared radiation level. As an object, such as a human, passes in front of the background, such as a wall, the temperature at that point will rise from room temperature to body temperature, and then back again. This quick change triggers the detection.

    Playback calculations based on the 16Mbits of memory
    A playback time of 4 minutes can be achieved with an MP3 file that has a Bitrate value of 64Kbps.
    A playback time of 2 minutes can be achieved with an MP3 file that has a Bitrate value of 128Kbps.
    A playback time of 1 minutes can be achieved with an MP3 file that has a Bitrate value of 256Kbps.
