5pcs LM393 3 Pin IR Flame Detection Sensor Module Fire Detector Infrared Receiver Module

Features 1 The flame sensor is most sensitive to flame and it will also respond to ordinary light generally used in fire alarm and other purposes 2 A small panel output interface can be directly connected with the microcontroller IO port 3 The sensor should be kept a certain distance from the flame so as not to damage the sensor because of high temperature 4 the test distance for thelighter flame should be 80cm the larger the flame the larger the test distance 5 Small plates analog output mode and the AD conversion process can help get higher accuracy 6 With an adjustable precision potentiometer to adjust the sensitivity 7 A fixed bolt hole is set for easy installation Specifications Flame or the light with the wavelength 760 nm to 1100 nm The detection angle 60 degrees extremelty sensitive to the flame spectrum Sensitivity adjustable shown in blue digital potentiometer Driving ability Up to 15mA Operating voltage 3 3V 5V The output form DO digital switching outputs 0 and 1 and AO analog voltage output PCB Size 3 2cm x 1 4cm Package Included 5 x 3 Pin IR Flame Detection Sensor
