It can detect flame or light source with wavelength in the range of 760 nm to 1100 nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is.
The detection angle is about 60 degrees, which is especially sensitive to the flame spectrum.
Sensitivity is adjustable (blue digital potentiometer adjustment in the figure)
Comparator output, clean signal, good wa veform, strong driving capability, over 15mA
With adjustable precision potentiometer to adjust sensitivity
Working voltage 3.3V-5V
Output form: DO digital switch output (0 and 1) and AO analog voltage output
With fixing bolt holes for easy installation
Small board PCB size: 3.2cm x 1.4cm
Use wide voltage LM393 comparator
Module instructions:
The flame sensor is most sensitive to the flame and also responds to ordinary light. It is generally used for flame alarms and other purposes.
The small board output interface can be directly connected to the IO port of the single chip microcomputer.
The sensor and the flame should be kept at a certain distance to avoid damage to the sensor at high temperature. The flame distance of the lighter is 80cm. The larger the flame, the farther the test distance is.
Small board analog output mode and AD conversion processing can achieve higher precision
