CWM_v2 - Clean Water Monitoring evolution

Drinking water is essential to human health. However, contamination still occurs in distribution networks, particularly due to the time lag between occasional laboratory analyses. While many parameters are continuously monitored at drinking water production facilities, water quality is subsequently checked only intermittently throughout the network. Several studies therefore highlight the need for online monitoring.

This project is an evolution of an initial version developed in 2018. It aims to design a precise, autonomous, and easily installable multi-parameter sensor for use in water pipes, with controlled costs and reduced maintenance.

This new probe incorporates revised and improved versions of existing sensors for temperature, pressure, conductivity, bidirectional flow, turbidity, and residual chlorine, and also includes a novel pH sensor.

The sensor, powered by a battery with a lifespan of approximately one year, transmits data via the LoRa network to a monitoring center, enabling continuous monitoring with alerts if thresholds are exceeded.
