Water is inexpensive. In Europe and North America, one cubic metre of drinking water costs between € 0.50 and € 2.50. It is important that drinking water remains affordable for everyone because access to clean water is a basic human right. But there is a downside: because the price of water is so low, we forget how precious it is.
Sensor technology offers a great opportunity to create public awareness of the value of water.
Using smartphone apps and low-cost sensors, farmers, citizens or other stakeholder groups can be involved in local water quality monitoring campaigns or become more aware of their own water habits.
