LM393 4 Pin IR Flame Detection Sensor Module Fire Detector Infrared Receiver Module for arduino Diy Kit -Blue The flame sensor is most sensitive to flame,and it will also respond to ordinary light,generally used in fire alarm and other purposes. A small panel output interface can be directly connected with the microcontroller IO port. The sensor should be kept a certain distance from the flame,so as not to damage the sensor because of high temperature. the test distance for thelighter flame should be 80cm,the larger the flame,the larger the test distance. Small plates analog output mode and the AD conversion process can help get higher accuracy.
