Features:
Can detect a flame or
the light
of
760
~ 1100nm
wavelength
, lighter flame test distance of 80cm, for the greater
flame, the farther the distance test.
The
detection angle is about 60 degrees, particularly sensitive to the flame spectrum.
S
ensitivity is adjustable (shown in blue digital potentiometer adjustment).
Comparator output, signal clean, good waveform, strong driving ability, more than 15mA.
W
ith adjustable precision potentiometer for sensitivity adjustment.
With fixed bolt holes for easy installation.
Specifications:

Wiring instructions:
Product wiring description:
VCC:
3.35V
power supply "+"
GND: power supply ""
DO: TTL switch signal output.
AO: analog signal output (voltage signal)
Instructions for use:
1. the flame sensor is most sensitive to
flame, for
ordinary light, it is also responsive
, generally used as a flame alarm purposes.
2. the output interface can be directly connected to the microcontroller IO port.
3. The sensor must be kept at a distance from the flame to avoid damage to the sensor.
lighter flame test distance of 80cm, for the greater
flame, the farther the distance test
4. Analog output and the AD conversion process, can achieve higher accuracy
5. When the sensor detects a flame, sunlight, or infrared light, if achieve potentiometer setting threshold, the green indicator light will ON, the DO output low level (00.1 V), the green light is OFF, the DO output about 3 V high voltage level
