An Open Source Hardware/SoftwareLow-Cost Weather Station

I Arduino: Micro-controller

I Sensors: Rain, wind, temperature, humidity

I Local: 80+% made in the country of use by SMEs

I Local: Maintenance & spare parts with local SMEs

I Local: Local shop sells rural solar power kit

I Local: Local blacksmith for steel work

We work with a rural tank manager from irrigationdepartment for realtime rain alerts.Red Cross is evaluating the concept for a project in Togo.Other countries are evaluating for other applications.
