GOLDEN FALCON ELECTRONIC.CO

Input voltage: DC5V, power consumption (current): 150mA

Do output: TTL digital quantity 0 and 1 (0.1 and 5V)

Ao output: 0.1-0.3v (relatively pollution-free), maximum concentration voltage about 4V

Special reminder: after the sensor is powered on, it needs to be preheated for about 20s before the measured data is stable. The heating of the sensor is a normal phenomenon, because there is an electric heating wire inside, if it is hot, it is abnormal.
