In 2020, driven by the scarcity of sensors with home automation connectivity, I began developing the first MoreSense air quality sensor, the MoreSense MS-01. Although MoreSense products are still technically classified as DIY, they have evolved into professional and reliable sensors, offering far more features than those typically found in standard products.

The MoreSense MS-06 is designed to measure carbon dioxide (CO₂), temperature, and relative humidity. The sensor features a 2.8-inch resistive touchscreen for displaying measurements and making settings. The MS-06 uses the Sensirion SCD40 sensor, known for its precision and compact size, utilizing photoacoustic non-dispersive infrared sensor technology.

The sensor can optionally be connected to a WiFi network (not mandatory) and can be linked to many home automation systems, including Domoticz and Home Assistant, using MQTT or REST. Both Domoticz and Home Assistant support autodiscovery (via MQTT), allowing the sensors to be automatically added. It can also be connected to Homey. For Homey, no MQTT server is required, but the HomeyDuino app (available for free in the Homey app store) is needed. Measurements can also be retrieved using an HTTP GET command (REST), with the data returned in JSON format.

This sensor can be used to control a ventilation system, potentially leading to significant savings. In winter, you don’t need to exhaust your valuable warm air if it’s not necessary. Control is possible via your home automation system or directly through smart plugs. A suitable smart plug is also available if needed.

Key Features Overview

• Fast ESP32 S3 240 MHz dual-core microcontroller with 8-bit parallel 2.8-inch touchscreen
• Sensirion SCD40 based on photoacoustic NDIR technology
• Precise CO2 measurements up to 2000 PPM (+/- 50 PPM 5%)
• Maximum value up to 40000 PPM (less accurate)
• Sensor lifespan >10 years (according to Sensirion)
• Comparative tests with the Aranet4 (widely recognized as the most accurate in its class) show nearly identical results. This sensor is therefore as accurate as the Aranet4.
• Temperature & humidity
• Measurement history via clear graphs (24 hours on the sensor, +/- 1 year via web interface)
• Virtually unlimited history with a microSD card (not included)
• 2 customizable CO2 alarm levels for acoustic alarms and color display meters
• Automatic calibration or calibration using a user-defined reference value
• Automatic calibration can be disabled.
• Manual calibration based on outdoor air is also possible
• Built-in web server for reading values, adjusting settings, and performing firmware updates
