We are up and running February 4th, 2025
Finally the new weather station is installed and operational. We are not transmitting the information yet because there are still some adjustments to be made but, in principle, everything is functional. The weather station uses three main components: Ecowitt Temp & Humidity & Solar & Wind & Rain (WS90 7-in-1 Outdoor Solar Powered Weather Sensor), Ecowitt GW2000 Wi-Fi Gateway set to transmit to MQTT and Winsen ZPHS01B Multi-in-One Sensor Module for CO2, PM2.5, CH2O, O3, CO, TVOC, NO2 Temperature, Humidity Detection Sensor connected to an ESP32 that transmits to MQTT. The weewx software uses the wxMesh driver (https://github.com/morrowwm/weewxMQTT/tree/master) to allow data collection from different sources and the database schema has been modified to allow the storage of pollution information. To calculate the air pollution index, the weewx-aqi-xtype extension (https://github.com/bellrichm/weewx-aqi-xtype) was used, to which support for other pollutants than PM2.5 and PM10.0 (CO, NO2 and O3) was added.
