A Low-Cost IoT System for Water Quality Monitoring in Developing Countries

Continuous monitoring can allow early warning of abnormal behavior in water quality parameters for different uses. In developing countries where monitoring capacity is limited or absent, supporting water quality verification is essential. This work proposes a low-cost, real-time telemetry system based on Internet of Things (IoT) technologies to monitor water quality parameters. This work proposed an architecture for a wireless IoT system with a microcontroller, water sensors, Wi-Fi transceiver and a web application that allows monitoring from the internet. We implemented an early use case in water monitoring for aquaculture in El Salvador.
