Abstract	This paper introduces an IoT-based, real-time water quality monitoring solution with low power demands, specifically based upon ESP32 microcontrollers with the ESP-NOW protocol. This system allows for effective, remote measurement of important water quality variables - including Total Dissolved Solids (TDS) and turbidity - without requiring conventional Wi-Fi infrastructure. The system is designed with an emphasis on being scalable, having low power requirements, and with the ability to function in remote or rural areas, making it a low-cost solution that measures can be easily utilized for long-term environmental monitoring.
