Gas:Bit – Gas Sensor for MicroBit (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 (or Breakoot as we say in Scotland) Board for the BBC Micro:bit (microbit) is a simple to use, best-seller 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 Proto-PIC 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 BBC 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!

Please note: This board does NOT come with any sensors or micro:bit. You will need to attach a BBC Micro:Bit and a gas sensor. These can be purchased separately from Proto-PIC.

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

Sample uPython code :

from microbit import *

# ‘Flame’ animation graphics
firea = Image(“00900:”
“00990:”
“09590:”
“95959:”
“09990”)

fireb = Image(“00900:”
“09900:”
“09590:”
“95559:”
“09990”)

# Wait for 60 Seconds – allow sensor to heat up
for x in range(0,60):
display.show(firea)
sleep(500)
display.show(fireb)
sleep(500)

threshold = 800

while True:
reading = pin2.read_analog()
if (reading > threshold):
display.show(Image.HAPPY)
else :
display.show(Image.SAD)
