USES:Various kinds of flame, fire detectionThe module features:1, can detect the flame or wavelength at 760 nm to 1100 nm range of light, the lighter the test flame distance is 80 cm, on the flame, the greater the distance test2, the detection Angle of 60 degrees or so, particularly sensitive to the flame spectrum3, the sensitivity adjustable digital potentiometer to adjust (blue)4, the comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma5, with adjustable precision potentiometer sensitivity adjustment6, the working voltage of 3.3 V to 5 V7, output form: DO digital switch output (0 and 1) and AO analog voltage output8, has a fixed bolt hole, convenient installation9, small board PCB size: 3.2 cm x 1.4 cm10, use the LM393 wide voltage comparatorModule USES:1 the most sensitive to the flame, flame sensor, also responds to ordinary light, generally used for fire alarm purposes.2, small plate output interface can be directly connected to a microcontroller IO port3, sensor and fire to keep a certain distance, to avoid the damage of high temperature sensors, distance of the test flame for lighter is 80 cm, on the flame, the greater the distance test

4, small plate analog output mode and AD conversion processing, can achieve higher precision
