A device that crowd-sources water quality could help prevent the spread of diseases such as cholera.
The Water Canary checks supplies in real-time, alerting users to possible infections.
It is also able to upload the data, allowing scientists to monitor the location and movement of outbreaks.
Unveiling the device at the TED Global conference in Edinburgh, researchers said they hoped eventually to give the units away for free.
More than three million people die each year from water-related disease, according to the World Health Organisation.
"Water Canary is an open source tool to rapidly test water and transmit information in real time to be instantly assessed," said co-founder and TED fellow Sonaar Luthra.
He explained why such a device is needed.
"Currently water testing is too slow and too expensive. We only test water in hindsight," he told the BBC.
"When cholera hit Haiti there was no way of knowing how fast it would spread," he added.

The sanitation ladder is a useful tool that is being used to monitor progress towards the sanitation target of the MDGs. This tool could be even more useful if it can be refined to be based on the functions of sanitation systems rather than on a hierarchy of predefined sanitation technologies. This paper presents a seven-rung function-based sanitation ladder where the functions can be broadly divided into health functions and environmental functions. The proposed ladder is intended as an inspiration for nations, and the JMP, to move towards a function-based rather than technology-based monitoring of sanitation progress. A functional approach to monitoring of e.g. the sanitation target of the MDGs would require some major shifts in the monitoring methods used but it is argued that such an approach would: (i) actually monitor the public good, which is desired from a sanitation system; (ii) stimulate donors, governments and municipalities to think beyond the provision of certain sanitation technologies; (iii) allow for local solutions to the sanitation problem to be developed; and (iv) spur innovation within the sector.
