This paper analyses solar radiation, wind and water flow as energy sources that can be explored to meet the energy needs of a wireless sensor network router within the context of precision agriculture. It also describes a multi-powered platform solution for wireless devices. The prototype can manage simultaneously the three energy sources and is capable of permanent operation. The energy scavenging techniques double up as sensors, yielding data on the amount of solar radiation, water flow and wind speed, avoiding the need for specific sensors.
