A low-cost IoT sensor kit to measure surface water quality in rural Africa


Good drinking water is essential for all. However, in e.g. rural Africa the quality of water, for example from wells is not always reliable. Lab water testing and existing tools are expensive and time consuming.

Allard Oelen developed a low-cost sensor kit, for the rural context of rural Africa. The IoT sensor measures a number of parameters that can help to identify changes in the water quality. Although it cannot detect any possible pollution of water, the kit can give a good indication of possible risks in water quality, especially when changes in water quality occur. The data can be accessed online. The kit was tested in Burkina Faso. See also Allard Oelen’s master thesis.
