  • Model: SEIR-01


This Infrared Obstacle Avoidance Sensor returns a signal when it detects an object in range. The range of the sensor is around 2-40 cm is distance. It operates at 3.5 to 5 volts at around 20 milliamps. The Obstacle Avoidance Sensors usually come in two types - with 3 and 4 pins. The 3 pin version does not have the ability to be enabled/disabled. The 4 pin version has optional Enable pin. Infrared obstacle avoidance sensor is designed to detect obstacles or the difference in reflective services. One application is to help a wheeled robot avoid obstacles with a sensor to react to adjustable distance settings. This device has an infrared transmitter and receiver, that forms the sensor pair. The transmitter LED emits a certain frequency of infrared, which the receiver LED will detect. The receiving LED will detect some of the signal back and will trigger the digital on/off “signal” pin when a specific threshold “distance” has been detected. Most boards will have 2 potentiometers, one of which is to adjust how sensitive the sensor is. You can use it to adjust the distance from the object at which the sensor detects it. Typically, the other potentiometer, which changes the transmitter IR frequency is not adjusted.

  • Vcc: 3.3 to 5 Vdc Supply Input
  • GND: Ground Input
  • Out: Output that goes low when an obstacle is in range
  • Power LED: Illuminates when power is applied
  • Obstacle LED: Illuminates when obstacle is detected
  • Distance Adjust: Adjust detection distance. CCW decreases distance. CW increases distance.
  • IR Emitter: Infrared emitter LED
  • IR Receiver: Infrared receiver that receives signal transmitted by Infrared emitter.
