Product description:

Graphene-based gas and vapor sensors have been attached much attention in recent years due to their variety of structures, unique sensing performance, room-temperature working conditions, and tremendous application prospects, etc.

Wiring: VCC: positive power supply (5V); GND: power supply is negative; DO: TTL switching signal output; AO: analog signal output

Specification:

  • MQ-7 CO Carbon monoxide Graphene-based Gas/Vapor Sensors Gas Detection Sensor Module
  • 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 the 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 a 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 the 20S to achieve stability in data measurement, the sensor does get heated up it is a normal phenomenon, because of the internal heating wire.
