Technology Solution: Flood early warning tool
This project is a collaboration between People In Need & DAI Maker Lab, with technical assistance funding from Development Innovations to support the development of an open-source flood early warning tool. This pilot project had two goals - 1) to develop a viable open source design suitable for scaling to other key locations around Cambodia to establish a national flood information network, and 2) to introduce the principle of open source hardware for development to stakeholders in Cambodia and build some basic skillsets for participating practitioners. The device, called Tepmachcha (https://github.com/DAI-Maker-Lab/tepmachcha/wiki), is a sonar stream gauge that, mounted on a fixed point over a stream such as a bridge, can determine the water’s height and send that information over a mobile phone network to the cloud for logging (http://ews1294.info/sensormap). If the stream’s height exceeds a warning level, Tepmachcha triggers an alert on PIN’s IVR system. The tens of thousands of IVR subscribers in the Tepmachcha pilot area will get a voice telephone call within a matter of minutes alerting them of the flood condition.
