More info

This is a multipurpose infrared sensor which can be used for obstacle sensing, fire detection, line sensing, etc and also as an encoder sensor. The sensor provides a digital output. The sensor outputs a logic one(+5V) at the digital output when an object is placed in front of the sensor and a logic zero(0V), when there is no object in front of the sensor. An onboard LED is used to indicate the presence of an object.


  • Range of around 25 cm
  • Input Voltage: 5V DC
  • Comes with an easy to use digital output
  • Can be used for wireless communication and sensing IR remote signals
  • Sensitivity can be adjusted using the onboard potentiometer.


Out of the three pins, the pin next to J1 is the GND pin, the middle pin is the VCC, and the pin near the LED is the 1OUT pin of the LM358 IC.
