An easy-to-read smart air quality monitor that helps you spot poor indoor air at a glance and alerts you when it matters.
This air quality monitor keeps track of particulate pollution in your home and notifies you when levels rise. It continuously measures PM2.5 or PM10 particles, tiny inhalable pollutants linked to issues such as asthma, heart disease and lung problems, alongside temperature and humidity. Alerts can be delivered visually, audibly, or via your favourite Matter-compatible smart home platform, making it easy to take action when air quality changes.
The device features a clear LCD screen to view the particulate levels and is powered via USB-C, with a short cable included.
Get Smart, Automate!
This is a smart sensor, so the fun really begins when you connect it to your home automation system.
You can create rules based on temperature, humidity or particulate levels, triggering notifications or actions such as turning an air purifier on or off, or opening a window. At a glance, you can check air quality throughout your home and view historical sensor data.
Sonoff’s Matter over Wi-Fi devices can be used with their eWeLink app with no additional hardware required. They can also be added to other ecosystems such as Apple Home, Google Home and Alexa, and work with a Raspberry Pi running Home Assistant or a Home Assistant Green equipped with a Thread or Matter adapter.

Notes
- Note that this device has intake/exhaust vents on the sides and back so you should only use it with the built in stand, it's not suitable for wall mounting.
What is Matter?
Matter is a modern smart home standard that makes it easier for devices from different brands to work together reliably. Matter-certified devices like this one can be used across multiple platforms, including Home Assistant, Apple Home, Google Home and Alexa.
Matter devices are designed to work locally on your home network, so they do not rely on the internet or a cloud service to function. This means faster response times, improved reliability and better privacy.
Instead of using its own special radio tech like Zigbee or Z-Wave, Matter runs over standard home networking technologies like Wi-Fi, Ethernet, or Thread. This helps ensure long-term compatibility and makes it easier to mix and match smart home products from different manufacturers.
