Flame detection sensor module is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm. Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm. Detection point of about 60 degrees, particularly sensitive to the flame spectrum. Sensitivity is adjustable, stable performance.Features:• on board, digital output interface can be directly connected with the microcontroller io.• please keep a distance with flame, high temperature maybe burn out the sensor module. • 100% brand new and high quality• detection angle about 60 degrees, it is sensitive to the flame spectrum.accuracy adjustable• operating voltage 3.3v-5v• output: 1. Analog voltage output, 2. Digital switch outputs (0 and 1)• with a mounting screw hole • pcb size: 3cm * 1.6cm• power indicator (red) and digital switch output indicator (green)• comparator chip lm393 ,it is stable.• flame detection distance, lighter flame test can be triggered within 0.8m, if the intensity of flame is high , the detection distance will be increased.Directions: • + = 3.3v-5v voltage• - = gnd• do = board digital output interface (0 and 1)Ao = board analog output interface
