wed-20The main purpose of WED is to help humanity to map clean water resources and avoid flooding. Our secondary purpose is provide a global network of accurate atmosphere and water conditions in every point on the planet Earth.
This project is solving the Clean Water Mapping challenge. Description
The main purpose of WED is to help people have access to safe drinking water. There are currently more than 1000 million people in the world that lacks access to an easily accessible and safe water source, such as a connection to water mains or a protected well. Instead, water access is limited or available through unprotected sources
We use a low-cost microprocessor and a combined sensor temperature - humidity with absolute limits from -20 to +50 degrees Celsius and 5 % to 95 % RH, soil humidity with FC-28 sensor. The module uses a standard Li- ion battery at 3.7 V and can be charged via MicroUSB plug and via sunlight using a solar panel. The connection is established via Wi-Fi modul (Electric Imp which is providing connectivity for the Internet of Things). The combined cost of this is about 64 USD. The code is opensource and we use Arduino IDE for developing. The whole scheme can be easily reproduced using just Arduino and few other sensors.
We are developing better modes for our device, with the aim to lower the battery consumption ( our device works 5 days with one charge and no solar panel, we are trying to make it work about a month without charging). We are also trying to lower the price of the components, our aim is 15 USD (price without the solar panel).
