Microduino-Air-quality

The product number of Sensor-Air is: MSDT61

Sensor-Air is an air quality sensor module.

TP401T air quality sensor shows great sensitivity towards alcohol, cigarettes, ammonia, sulfide and other pollution sources.

Introduction of Sensor Pins

Pins of the sensor: PIN1: GND PIN2: VCC General signal pins: PIN3(IO1): digital/analog signal PIN4(IO2): NC(null) Special signal pins: If it is IIC: IO1/IO2 are respectively SDA/SCL. If it is soft serial port: IO1/IO2 are respectively tx/rx.

Special to Sensor-Air Quality sensor pins PIN1: GND PIN2: VCC PIN3(IO1): Analog signal read PIN4(IO2): NC Microduino sensor can communicate with core module through the connection with Microduino-Module Sensor Hub.
