Interface IR Distance Sensor With AVR

Description

  • Infrared sensors find numerous applications in electronic systems.
  • IR sensor has two parts, IR transmitter, and receiver.
  • The IR receiver detects the IR radiations transmitted by an IR LED.
  • The output voltage level of the IR sensor depends upon the intensity of IR rays received by the receiver.
  • The sensor’s output in its original analog form.
  • The output of the IR sensor is processing through ADC.
  • The ADC is calibrated to get almost accurate distance measurement.
