IR Infrared 4 Wire Flame Detection Sensor Module Flame Sensor Module Features: 1. Can detect the flame or the wavelength at 760 nm to 1100 nm range of the light source, the test flame lighters distance of 80cm, the larger the flame, the greater the distance test. 2. The detection angle of 60 degrees, the flame spectrum particularly sensitive. 3. Sensitivity adjustable.
