ACROBOTIC NO2 Gas Sensor Breakout Board (MiCS-2714)

Regular price $29.95

The MiCS-2714 (datasheet) is a sensor that detects changes in the chemistry of surrounding air using an accurately micro-machined diaphragm with an embedded heating resistor, and a sensing layer on top.

The actual detection process of the gas is done by measuring the sensing resistance of the sensor, which increases in the presence of Nitrogen Dioxide.

Because the sensor comes as a Surface-Mount Device (SMD), our Breakout Board gives easy access to all of its pins. In addition, the board includes the necessary resistors (as recommended by the sensor's manufacturer) both for the load and the sensing electrical circuits.

Please note that the MiCS-2714 sensor on this board is a suitable replacement for the discontinued MiCS-2710 Sensor (datasheet), which we no longer sell!

As with all of our Breakout Boards the pin headers are included, but they're not soldered in to allow for different use cases!


The MiCS-2714 is a sensor whose resistance varies in the presence of small concentrations of NO2. This value varies between 2kΩ and 2MΩ approximately, providing high accuracy throughout the output range. The sensor's resistance in air, as well as its sensitivity, can vary between different units, so it is recommended to calibrate the sensor before including it in your application.


  • Measurement range: 0.05 to 5 ppm
  • Resistance in air: 0.8 to 8 kΩ (typically 2.2kΩ)
  • Sensitivity: 6 to 100 (typically 55; ratio between the resistance at 0.25ppm and in air)
  • Supply voltage: 1.7V to 2.5V DC
  • Operating temperature: -30 to +85 °C
  • Response time: 30 seconds
  • Average consumption: 26mA (throughout the complete power supply cycle)

This sensor is perfect for getting started with Environmental/Air Quality monitoring!
