The Qsen-07 multi-sensor board is an ESP32 wireless development board that combines several useful sensors into one device, making it easier to control, monitor, and enhance your home environment. It is a recent product from Maker Go, a China-based hardware company, which claims the board is “fully integrated with ESPHome and Home Assistant“. But as noted in a reader’s comment below, ESPHome on ESP32-C6 is still a work in progress, and the YAML configuration file for the board has yet to be provided by the company.
The Qsen-07 multi-sensor board is “designed for health-conscious and tech-savvy homeowners” and can monitor air quality and other environmental variables to ensure a safe and smart living space. It features up to seven sensors, including two air quality sensors, a temperature and humidity sensor, an ambient light sensor, a barometric pressure sensor, an attitude gyro sensor, and an optional radar sensor.
The Aosong AGS10 VOC (Volatile Organic Compound) sensor is used to detect indoor air pollutants such as ethanol, ammonia, benzene, etc, and Sensirion’s next-gen SCD40 sensor uses photoacoustic NDIR sensing to detect CO2 levels in the air. The BH1750 ambient light sensor detects the amount of ambient light present, allowing lighting to be adjusted to suit the user’s preferences.
The AHT20 (also from Aosong) is a high-precision, high-accuracy temperature and humidity sensor. A BMP280 absolute barometric pressure sensor monitors atmospheric pressure for indoor air quality and overall weather conditions and a 6-axis gyro sensor from QST solutions can monitor the board’s orientation in space. An optional 5.8G radar module is also included to monitor whether people are in the home.

It is compatible with the Arduino development platform and sends serial output via the Serial Monitor tool in the editor. The USB-C port on the board serves for powering and programming it. Documentation, schematics, and demo software are all available on the ICBbuy website. The product comes in a plastic enclosure that exposes the USB-C port and reset button.
We have previously covered other open-source, ESP32-based environmental monitoring devices, including Studio Luff’s Air Quality Sensor and the AirGradient ONE kit. The Qsen-07 is the first air quality monitoring board we have seen that is based on the ESP32-C6. The ESP32-C6-EVB quad relay board is another ESP32-C6-based board manufactured by Maker Go.
The Qsen-07 multi-sensor board is priced at about $45 and is currently on sale at 10% off. Maker Go’s Aliexpress store doesn’t currently feature their latest product but may include it soon.
