Post-harvest problems faced by farmers are drying grain. Traditional drying method, low-cost (dried) or use the dryer does not provide a perfect drying results. This is due to the two methods are not able to regulate the temperature, moisture content and humidity levels of the air to the right.

Ambient RF energy harvesting becomes one of the potential renewable energies for powering low power electronic devices such as autonomous sensors in wireless sensor networks (WSN). Comparing to other ambient energy sources, RF energy has the lowest density power, although it can be harvested all day and night. Our current research aims to build an RF energy harvesting system prototype using ultra...
