This 4 channel Infrared Obstacle Avoidance Proximity Sensors Module supports 4 IR transmitter and IR receiver pairs that sends out IR energy and look for reflected IR energy to detect presence of any obstacle in front of the sensor module. The module has on board potentiometer for each channel that lets user adjust detection range. The sensor has very good and stable response even in ambient light or in complete darkness.

The sensor module can be interfaced with Arduino, Raspberry Pi or any microcontroller having IO voltage level of 3.3V to 5V.

  • LM393 Comparator based detetction circuit is very stable and accurate
  • On board potentiometer sets obstacle detection range
  • On board Power LED indicator
  • On board Obsatcle Detection LED indicator
  • 3.0MM mounting hole for easy mounting the sensor.
  • Male header for easy connection
  • Good Accuracy: By use of Infra-red LED transmitter the module performs well in Ambient light

Technical Specifications

  • Number of channels: 4
  • Detection angle: 35 °
  • Operating Voltage: 3.0V – 6.0V
  • Working voltage: DC 3.3V-5V
  • Mounting aperture: M3 screws
  • Detection range: 1mm to 60 CM adjustable, the closer the performance more stable, white reflects the farthest distance.
  • Dimensions
    • Control Board of 42mm * 38mm * 12mm (length * width * height)
    • Sensor Board 25mm * 12mm * 12mm (length * width * height)
  • Output interface: 6 wire interface (1234 to 4 signal output ends, + positive power, – for the negative power is ground)
  • The output signal: TTL level (can be directly connected to I/0 microcontroller, infrared light reflected back to the sensor induction, the red indicator light, output low level; no infrared light, the indicator light does not shine, the output high.)
  • Current Consumption:
    • at 3.3V : ~23 mA / channel
    • at 5.0V: ~43 mA / channel
