Air Quality Sensor Hazardous Gas Detection Switching Transducer For

Air Quality Sensor Hazardous Gas Detection Switching Transducer For Arduino Description Using high-quality dual-panel design,with power indicator and TTL signal output instructions. The switching signal having a DO (TTL) output and analog output AO. TTL output valid signal is low. ( Low-level signal when the output light can be directly connected to the microcontroller or relay module ) Analog output voltage with the higher concentration of higher voltage There are four screw holes for easy positioning. Has a long life and reliable stability Rapid response and recovery characteristic 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 . Package Included 1 x Air Quality Sensor
