Digital IR Infrared Flame Thermal Temperature Sensor - OKY3053

This Flame Sensor is sensitive to the flame, but also can detect ordinary light. Usually used as a flame alarm. On board, digital output interface can be directly connected with the microcontroller IO. Features: - Detects a flame or a light source of a wavelength in the range of 760nm-1100nm;- 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.
