Key Highlights High sensitivity IR receiver Extremely sensitive to wave between 760-1100nm Power supply indicator lamp Comparator output indicator lamp Operating voltage of this sensor is 3.3V to 5V Analog quantity output Product Description This tiny Flame sensor infrared receiver module ignition source detection module is Arduino compatible and can use to detect flame or wavelength of the light source within 760nm~1100nm also useful for Lighter flame detect at a distance of 80 cm. Greater the flame, the farther the test distance. It has a Detect angle of 60° and is very sensitive to flame spectrum. It produces the one-channel output signal at the D0 terminal for further processing like an alarm system or any switching system. The sensitivity is adjustable with the help of a blue potentiometer given on the board. Onboard signal output indication, output effective signal is high, at the same time the indicator light up, the output signal can directly connect to microcontroller IO. The flame of the most sensitive sensors flame, the regular light is also a response, generally used for fire alarm purposes.
