Description:

• Flame sensor to fire the most sensitive to the ordinary light is also a reaction, general used as flame alarm purposes.
• Small plate output interface can and single-chip microcomputer IO port directly connected
• Sensor and flame to keep a certain distance, to avoid high temperature damage sensor, the lighter test flame distance is 80 cm, the flame is bigger, test the farther the distance

The module features:

• Can detect flame or wavelength in 760 nm to 1100 nm range of light source, lighter test flame distance is 80 cm, the flame is bigger, test the farther the distance
• Detection Angle 60 degrees or so, the flame spectrum especially sensitive
• Sensitivity adjustable (shown in blue digital potentiometer control)
• Comparator output, signal clean, waveform, driving ability, more than 15 ma
• Adjustable precision potentiometer sensitivity adjustment
• Working voltage of 3.3 V - 5 V
• Output form: digital switch output (0 and 1)
• Fixed bolt hole, convenient installation
• Small board PCB size: 3.2 cm x 1.4 cm
• Wide voltage LM393 comparator
