This module is an infrared detection system for smart cars, robots, and other automated mechanisms to provide a multi-purpose solution. The discreet infrared transmitter and receiver use the LM339 voltage comparator as a core device in the control circuit. This system has a variety of detection functions which help with various automation projects and application of small intelligent systems.



  • Working voltage: DC 3.3V-5V
  • Working current: try to choose more than 1A power supply
  • Working temperature: – 10C to +50C
  • Mounting aperture: M3 screws
  • Detection range: 1mm to 60 CM adjustable, the closer the performance more stable, white reflects the farthest distance.
  • Size: in the control panel of 42mm * 38mm * 12mm (length * width * height)
  • Small forward 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.)



  • Easy to install, easy to use
  • 4-way independent sensors
  • Module ≤ 10 mm in height
  • Safe operating voltage from 3 to 6 volts
  • The 4-way operating current of 30-55 mA
  • Onboard 5.1 Kohm pull-up resistor



  • 1 x Four-Channel Infrared Tracing / Tracking Module F233-01
  • 1 x Jumper Leads
  • 4 x Sensors
