flame wavelengths between 760 nm to 1100 nm infrared is most sensitive. Module has two outputs:1, AO, analog output, real-time output voltage signal on the thermal resistance2, DO, when the temperature reaches a certain threshold, the output high and low signal threshold adjustable via potentiometer Power supply: DC 3-5.5VAnalog output
