| 9 | Backscatter radio, or reflection radio, offers a low-cost and low-power alternative to conventional radio sensor networks. This is crucial for modern agriculture which requires continual monitoring of environmental conditions such as soil moisture or temperature. Prior research has been done using capacitance sensors to measure soil moisture and has shown promising results using backscatter radio, despite the limited range. |
