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

Sensor backpin.png

Air Quality Sensor
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
PIN3 (SIGNAL-A) Analog Input
PIN4 (SIGNAL-B) Not Connected
  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
  • Read more about the hub module.
