Measure changes in the concentration of gases including carbon monoxide (CO), nitrogen dioxide (NO2), and ammonia (NH3) with this Breakout Garden compatible I2C breakout.

The MICS6814 sensor comprises three semiconductor gas sensors in a single package, and can detect three different groups of gases that are referred to in the datasheet as reducing, oxidising, and NH3. The major gases/vapours that the sensor detects are: carbon monoxide (reducing), nitrogen dioxide (oxidising), and ammonia (NH3), but it is also sensitive to others, including hydrogen, ethanol, and hydrocarbons.

It can be used to make qualitative measurements of changes in gas concentrations, so you can tell broadly if the three groups of gases are increasing or decreasing in abundance. Without laboratory conditions or calibration, you won't be able to say "the concentration of carbon monoxide is n parts per million", for example. There's more info about the MICS6814 sensor and how it works in Pimoroni's Getting Started with Enviro+ tutorial.

This breakout uses a Nuvoton microcontroller which handles the I2C and analog-digital conversion, as well as controlling the sensor's inbuilt heater and the user controllable RGB LED. The LED could be used to indicate when the sensor is running or to notify you visually of gas concentration changes. It's Breakout Garden compatible, which means you can use it with any of our Breakout Garden HATs and pHATs - no soldering required!

It's useful for incorporating into indoor and outdoor air quality monitoring systems, especially if you're interested in monitoring agricultural and vehicle pollution levels.

Features

MICS6814 analog gas sensor (datasheet and FAQ)
Nuvoton MS51XB9AE MCU
RGB LED
2x M2.5 mounting holes
I2C interface, with a default address of 0x19.
3V to 5V compatible
Reverse polarity protection
Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)

Python library

Kit includes

MICS6814 Gas Sensor Breakout
1x5 straight male header
1x5 right angle female header

Pimoroni has designed this breakout board so that you can solder on the piece of right-angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).

Software

Pimoroni has put together a Python library together with examples showing you how to get readings from the sensor and control the LED.

Notes

Dimensions: approx 23 x 20 x 4mm (L x W x H)
