The MoreSense MS-06 is an ESP32-S3-based air quality monitor that takes CO², temperature, and humidity readings through a Sensirion SCD40 sensor which offers reliable performance and a lifespan of more than ten years.
The MS-06 monitor’s results are identical to the Aranet4’s (considered best-in-class), putting it in a pretty good spot accuracy-wise. It is the latest entry in the MoreSense line of air quality monitors and comes with a more compact design and a touchscreen display. The built-in web server runs an interface that displays measurements, historical data visualizations, setup options, and firmware updates. Operation is completely local; sensor data can be stored on the device or a microSD card.
The MoreSense MS-06 air quality sensor can be used to control a ventilation system, contributing to significant energy savings. This can be achieved through your home automation system or by using a smart plug.

The air quality sensor can be connected to a Wi-Fi network and linked to a home automation system via MQTT or REST. It supports Domoticz, Home Assistant, and Homey (via HomeyDuino).
It resembles other ESP32-S3-based environmental monitoring devices like the Qsen-07, AirGradient One, and Studio LUFF’s Air Quality Sensor. It is not open-source like the other products but may be better suited for beginners since it includes a detailed user manual. The Sensirion SCD40 sensor has been seen in other CO2 monitors such as the M5Stack Unit CO2 and the TeHyBug ESP8285.
According to the maker, the MoreSense air quality sensor will be available on Tindie from August 20th. It is priced at $119 and comes with a stand, stylus pen, USB adapter, USB cable, an enclosure, and the manual. The optional 2000mAh LiFePO4 battery will set you back about €10 or $11 extra. Shipping is free for buyers in the Netherlands and direct support from the maker is available. Buyers are also assured a one-year warranty and money-back guarantee.
