In this article, we will integrate the M5Stack Air Quality Kit with Home Assistant to monitor air quality.
Index
While air quality may not be a concern for everyone, those of us living in large cities or near industrial areas are increasingly worried about the air we breathe at home. This concern is not unfounded—numerous studies have shown that long-term exposure to pollutants can lead to respiratory diseases such as asthma and bronchitis. Over time, it can also shorten lifespan and increase the risk of chronic illnesses like lung cancer.
From this perspective, home automation can help mitigate these effects by monitoring air quality, sending alerts when pollution levels rise, or even activating ventilation or air purification systems. If you're concerned about overall environmental pollution, you can refer to indexes like the World Air Quality Index.
However, whether you distrust external data (for instance, if monitoring stations are conveniently placed in green zones) or simply want to measure the specific data in your own home, an air quality sensor is essential. When it comes to finding a sensor that is comprehensive, integrable, and reasonably priced, debates always arise.
M5Stack is a well-known brand that offers devices like the M5Stack CoreS3SE and the historically significant Atom Echo. In this case, we’ll integrate the M5Stack Air Quality Kit with Home Assistant. This device is based on the ESP32S3FN8 chip and can measure CO2, VOCs, PM1.0, PM2.5, PM4, and PM10 particles, along with temperature and humidity (though some reviews suggest the accuracy of the latter two may be questionable). It also features an e-ink display and a built-in battery.
By the way, while this article focuses on integrating the M5Stack Air Quality Kit with Home Assistant, you can also use it directly with your mobile device to monitor its readings. The video below explains the setup process.
To integrate the M5Stack Air Quality Kit into Home Assistant, you will need:
🥑 If you’re new to ESPHome, I recommend checking out the Academy workshop to get the most of it!
Follow these steps to integrate the M5Stack Air Quality Kit into Home Assistant:
1. In Home Assistant, go to your ESPHome plugin, click “New Device,” and then click “Continue.”
2. Name your device (e.g., “ Air Quality Kit”) and click “Next.”
3. Select “ESP32-S3” as the device type. You'll notice that a new block has been created for your device in the background.
4. Click “Skip” and click “Edit” on the device block above. Copy the code that appears and save it, as you will need some parts of it later.
5. Copy the following code (which I found on reddit and edited slightly) and replace the above code in ESPHome.

6. Important: This code does not include the credentials for connecting the device to your Wi-Fi and Home Assistant instance, so you will need to enter them manually. Specifically, I am referring to the following lines of code that you copied in step 4.
# Enable Home Assistant API
api:
encryption:
key: "bg6hash6sjdjsdjk02hh0qnQeYVwm123vdfKE8BP5"

7. What you need to do is find the corresponding lines in the code (at the beginning) and add the necessary information.
8. Now, click “Save” and “Install.” Select “Manual download” and wait for the code to compile.
9. When finished, select the “Modern format” option to download the corresponding “.bin” file.
10. Connect the M5Stack Air Quality Kit to your computer using the USB-C data cable via the port on the bottom.
11. Now go to the ESPHome page and click "Connect." In the pop-up window, select your board and click "Connect."
12. Now click on “Install” and select the '.bin' file obtained in step 9. Again, click on “Install”.
13. Go back to Home Assistant and navigate to Settings > Devices & Services. Your device should be discovered and appear at the top, ready for you to click the “Configure” button. If not, click the “Add Integration” button, search for "ESPHome," and enter your board’s IP address in the "Host" field.
If you navigate to Settings > Devices & Services > ESPHome and select the M5Stack Air Quality Kit, you'll find several entities providing information about air quality.
Additionally, the buttons on the device's top-left corner have also been exposed as entities. This means you can create an automation to trigger an action when you press them, such as activating your ventilation system.
To set this up, go to Settings > Automations and Scenes > Create Automation. In the "When" section, add a "State" trigger. In the entity field, select the one corresponding to your device (e.g., 'binary_sensor.airq_button_a'), and in the "To" field, choose "On." Then, simply add the desired actions.
On November 18, 2024, M5Stack opened its doors to individual visitors for the first time. More than 70 visitors from all around the world attended the event, with some showcasing their projects built with M5 products or sharing their stories with M5Stack.
The event began at 3:00 PM, with many visitors checking in and receiving their gifts—custom T-shirts featuring the M5Stack logo. After a group photo, the first agenda kicked off: The Factory and Office Tour.
The visitors were divided into three groups, with introductions provided in Chinese, English, and Japanese. M5Stack operates an all-in-one facility where product design, production, packaging, quality control, marketing, and shipping are seamlessly managed under one place. Visitors could take a close look at the whole flow.
In the show board area, we display all the products we've created so far, including the classic 5x5 stack series—such as M5Basic Core, M5Core2, M5Core3, and Stick series—like the M5StickC, along with the Stamp Series (M5Cardputer, M5StampFly), and the Atom series (M5Atom Echo), among others. M5Stack’s CEO, Jimmy Lai, also explains "What is M5Stack?"
M5Stack is an open-source hardware IoT solution provider, primarily focused on products built around the ESP32. We also offer a range of accessories and our own visual programming platform, UIFlow. The "M" in M5Stack stands for Module, "5" represents the 5x5 cm size, and "Stack" refers to their stackable design.
M5Stack is committed to delivering convenient, stackable and easy-to-use development components and tools, with at least one new product every Friday, we launch over 50 new products every year. We provide not only standard products, also customized products. Our partner includes Amazon, Microsoft, Arduino, SONY, etc.
After the tour, it’s time for the Meetup. This year, we have 9 speakers. Jimmy began by sharing the company’s history, followed by presentations from the speakers. TAKASU Masakazu shared the success stories of M5Stack in Japan, where the Japanese market accounts for 35% of M5Stack’s global sales. Many companies and schools in Japan use M5Stack products, and you can even find books on how to use M5Stack products on Amazon.
Other speakers introduced their innovative projects, including the Creative Dot Matrix Clock, the M5Unified Library, M5Cuffbox, and the Blue Tears Incubator, how to make stack-chan bigger, etc.
It was a truly enjoyable experience to come together with M5Stack fans from all over. We appreciate everyone’s enthusiasm and participation, and we’re already looking forward to welcoming you again next year. See you then!
気分転換と運動を兼ねて、1ヶ月前に自転車を買って夕方に走っているのですが、今日は超音波風速計を載せてみました。

「ｴｱﾘｱﾙ･ｽﾀｯｸﾁｬﾝ」or「ｴｰﾙｽﾀｯｸﾁｬﾝ」。
見た目から期待した通りATOM Matrixと同じ形状なのでそのまま載せられました。
但し、6軸慣性センサー(MPU6886)を高速で読み出したり測定域を変えたりするために、ATOM_S3ライブラリに若干の修正が必要でした。 pic.twitter.com/cxEPzmVa6b
