Implementation Notes
Overview
The Solar-Powered Weather and Air Quality Monitoring Station is a standalone environmental monitoring system designed for continuous field data collection.
It uses an ESP32 controller, RS485-connected sensors, and GSM communication to collect and transmit weather and air-quality measurements from remote locations.
Parameters Monitored
The system measures:
- temperature
- relative humidity
- CO₂ concentration
- light intensity
- wind speed
- wind direction
- PM2.5
- PM10
Power System
The complete station operates from a 12 V solar-powered system with battery storage.
The power system is designed to provide approximately seven days of backup operation under the intended operating conditions, supporting continued monitoring during periods of low solar availability.
Communication
RS485 is used between the ESP32 and field sensors for reliable wired communication, while GSM provides remote connectivity for transmitting collected data to a server or monitoring platform.
Sensors → RS485 → ESP32 → GSM → Remote Server / Dashboard
This makes the station suitable for locations where Wi-Fi or fixed internet infrastructure is not available.
