Solar powered weather station with air quality monitoring

Matteo Monsello and Daniel Garčević built a solar-powered weather station with a particulate sensor to monitor air quality in Alba. It’s a modular design using ATmega328P microcontroller and uses the ESP8266 Serial-to-Wifi chip to upload the weather data to the ThingSpeak server. The weather station receives power from a 20W solar panel that charges a 12V lead acid battery using a custom built solar charge controller. The total cost to build it was around 300€.
