Beautyforall 2 pcs LM393 760nm - 1100nm IR Infrared Flame Sensor Module Board For Arduino

Description

Feature: Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm Detection angle about 60 degrees, it is sensitive to the flame spectrum. Accuracy adjustable Operating voltage 3.3V ~ 5V Output -Analog voltage output -Digital switch outputs (0 and 1) With a mounting screw hole 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. Interface(4-wire): VCC: 3.3V ~ 5V GND: GND DO: board digital output interface (0 and 1) AO: board analog output interface Size: 3.2 x 1.9cm Note: Please keep a distance with flame, high temperature maybe burn out the sensor module. Package included: 2 x Flame sensor module
