MoboSens: A water pollution sensor for your smartphone

MoboSens will give anyone with a smartphone the ability to measure the concentration of common pollutants – like nitrate, arsenic, chromium, lead – in water (municipal supply, private wells) and even soil (if properly prepared). The platform will enable them to share that information through the Internet. How that data improves human health and safety, as well as fosters more effective regulatory systems, could be revolutionary.
About the Project

Water quality is a global concern. Almost 1 billion people lack access to safe drinking water and 2 million die every year from unsafe water. Even in the United States, it is estimated that as many as 2,000,000 households have drinking water with dangerously high levels of nitrate, a serious threat to infants (methemoglobinemia, more commonly known as “blue baby syndrome”, inhibits oxygen transport by red blood cells).

Due to adverse environmental impacts from industry, inadequate and aging municipal infrastructure, and general shortcomings of regulatory systems, there is an express need for everyday citizen’s to take more responsibility in the monitoring the environmental health of their world. Beyond our own health and safety, this need is especially vital if we want to ensure a sustainable future for our children. However, the scientific equipment and technical training required to accomplish this task is beyond the reach of most citizens, even in wealthy nations like the United States. In response to this great social need, we’re developing a low-cost, high-accuracy, and extremely versatile sensor technology that makes use of nanotechnology and integrates with mobile devices: MoboSens.
