Station connectée de mesure de la qualité de l'air (réseaux LoRa Mesh (Meshtastic, Meshcore …))
Air quality remains a global concern despite local improvements. Air pollution is one of the greatest health risks, affecting almost every organ in the body. The impacts are particularly severe for children, the elderly, and populations exposed over long periods. It is responsible for approximately 7 million premature deaths per year worldwide (WHO). This is more than malaria, HIV, and road accidents combined.
The goal of the project is to develop the 2026 version of the “Air Quality Station,” which will transmit environmental measurements via the Meshtastic LoRa mesh network. Several environmental sensors are already supported by the Meshtastic firmware.
- Fine particulate matter sensor Plantower PMS7003
- Fine particulate matter sensor Sensirion SEN5X
- CO₂ sensor
- Grove Multichannel Gas Sensor v2 (CO, NO₂, C₂H₅CH, VOC)
- Ambient light sensor Vishay VEML7700
- Digital temperature and humidity sensor Sensirion SHT31
- High-precision temperature sensor Maxim MAX30205MTA / MAX30205
- Temperature sensor MAX31865 for PT100–PT1000 probes
- and more
Microcontrollers will be Wio E5, Microbit (nRF52), XIAO ESP32S3 and Sensecap Solar P1 Pro.
