Specification:Operating voltage:3.3V-5VUsing LM393 comparator with wide voltageA small panel output interface can be directly connected to the microcontroller IO portWith an adjustable precision potentiometer to adjust the sensitivityThe flame sensor is most sensitive to flame and it will also respond to ordinary light, generally used in fire alarms and other purposes.A small panel output interface can be directly connected to the microcontroller IO port.The sensor should be kept a certain distance from the flame, so as not to damage the sensor because of high temperature.the test distance for the lighter flame should be 80cm, the larger the flame, the larger the test distance.Small plates analog output mode and the AD conversion process can help get higher accuracy.Can detect flame or light with a wavelength at the range of 760 nm to 1100 nm.The detection angle is about 60 degrees, extremely sensitive to the flame spectrum.Sensitivity is adjustable. (shown in blue digital potentiometer)The comparator outputs a clean signal, good waveform, and a strong driving ability of more than 15mA.With an adjustable precision potentiometer to adjust the sensitivity.Operating voltage:3.3V-5V.A fixed bolt hole is set for easy installation.Using LM393 comparator with wide voltage.
