Ir sensors like all other photosensor work on the principle that a photon of sufficient energy can knock out electrons so that the resistance of the circuit is changed. Here we will discuss the introduction to ir infrared flame sensor module pin diagram hardware overview circuit diagram working principle its specifications and applications. So this circuit can be built with two transistors like npn and pnp.
Working of the project.
In this quick tutorial we are connecting ir flame sensor ky 026 with arduino to make fire or flame detector using a buzzer or led light to create an alert. This flame sensor is extremely sensitive to ir wavelengths between 760 1100nm light. Arduino uno checks the logic level on the output pin of the sensor and performs further tasks such as activating the buzzer and led sending an alert message. You can see the connections in the ir sensor circuit diagram.
