CentIoT - MQ-135 Air Quality Sensor Hazardous Gas Detection Graphene-Based Gas/Vapor Sensor Module (MQ 135)

Brand: CentIoT

Features:

• MQ-135 Air Quality Sensor Hazardous Gas Detection Graphene-based Gas/Vapor Sensor Module (MQ 135)
• 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
• 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
• Special note: After the sensor is powered, the sensor needs to warm up around 20S to acheive stablility in data measurement, the sensor does get heated up it is a normal phenomenon,because of the internal heating wire.
