SPECIFICATIONS

Input voltage : DC5V Power consumption ( current ): 150mA

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

AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V

Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal .

VCC: positive power supply (5V)

GND: power supply is negative

DO: TTL switching signal output

AO: analog signal output
