In this project we are using an IR based flame sensor. Then we use an Op-Amp to check for change in voltage across the IR Receiver, so that if a fire is detected the output pin (DO) will give 0V(LOW) and if the is no fire the output pin will be 5V(HIGH). When fire burns it emits a small amount of Infra-red light, this light will be received by the Photodiode (IR receiver) on the sensor module. Some of them are: Ultraviolet detector, near IR array detector, infrared (IR) detector, Infrared thermal cameras, UV/IR detector etc. There are different types of flame detection methods.

'Somebody there!', and also the buzzer turns on sounding the alarm and the LED also turns on. In the video, intially when there is no object in-front of the IR sensor a message 'No Obstacle!' on the LCD is displayed. Video Demonstration of IR sensor with Arduino, Buzzer, LCD & LEDįirst watch the video demo so that you know what you can expect from this tutorial. The LCD, IR sensor with buzzer Arduino code is provided at the end. Thus giving us both visual and audio signals to indicate that the sensor has detected something. In this project when the proximity IR sensor detects presence of nearby object, the LCD will display a warning message, the Buzzer will sound alarm and the LED will turn on. Here we will show how to interface IR sensor with Arduino, LCD, Buzzer and LED. They can be used as obstacle detection in Robotics, for parts detection in automated conveyors in industrial production line, for intrusion detection, opening and closing of doors and many others.

IR proximity sensors or Infrared sensors are useful in different kinds of projects.
