Hot Solder Gas:Bit – Gas Sensor Breakout Board for BBC Micro:bit - MQ Sensor Range

Our Gas:Bit enables you to easily add a gas sensor to the BBC micro:bit, hence Gas Sensor for microbit. This Gas Sensor Breakout Board for the BBC Micro:bit is a simple to use, and very popular with schools for a range of chemistry, physics, and science projects. The gas:bit adds a range of gas detection capabilities to the Micro:Bit, including hydrogen, methane, propane, smoke & more. Manufactured by Hot Solder in Scotland, the Gas:Bit is designed to interface with the MQ-3, MQ-4, MQ-6, and MQ-8 gas sensors which all use the same footprint. The gas:bit MQ gas sensor breakout board is a very economical and easy-to-use add-on for the Micro:Bit, in order, to detect a range of gases including butane or propane, compressed natural gas or butane, alcohol or benzine, and flammable gas. The MQ gas sensor breakout board for the Micro:bit, connects to an analog input and gives you a reading based on the concentration of the detectable gas. The gas:bit will not give you a PPM reading due to the resolution of the analog input, but can be great for detecting if the gas is in the air! We have used it with an alcohol sensor to make our own breath alcohol detector, giving an output when the concentration of alcohol on the breath was over a given value!

Use the Gas:Bit with the Following Sensors:

MQ8 – Hydrogen
MQ6 – LPG (Butane or Propane)
MQ4 – Methane or Compressed Natural Gas
MQ3 – Alcohol or Benzine
MQ2 – Flammable Gas and Smoke High Sensitivity for LPG, Propane, and Hydrogen
MQ9 – Carbon Monoxide and Flammable Gas Sensor


  • It has good sensitivity in a wide range
  • Has long lifespan
  • Low cost and simple drive circuit
