A printed capacitance sensor for soil moisture measurement
A printed capacitance sensor for soil moisture measurement
TDR (Time Domain Reflectometry) has been shown to give a good measurement of soil moisture by measurement of permittivity. However, TDR is expensive and power-hungry. This work describes an alternative approach to designing a soil moisture sensor that is also using the dielectric constant, but tackles some of the drawbacks of TDR. The aim is to infer the water content in soil by obtaining it's permittivity via the measurement of the capacitance of a PCB capacitor. The simple design of the sensor allows mass-manufacturing at a low cost, enabling a large number of the sensors to be deployed networked. This makes it ideal for those requiring soil moisture monitoring over a large area such as farmers, to do so without a large financial cost.

Abstract
TDR (Time Domain Reflectometry) has been shown to give a good measurement of soil moisture by measurement of permittivity. However, TDR is expensive and power-hungry. This work describes an alternative approach to designing a soil moisture sensor that is also using the dielectric constant, but tackles some of the drawbacks of TDR. The aim is to infer the water content in soil by obtaining it's permittivity via the measurement of the capacitance of a PCB capacitor. The simple design of the sensor allows mass-manufacturing at a low cost, enabling a large number of the sensors to be deployed networked. This makes it ideal for those requiring soil moisture monitoring over a large area such as farmers, to do so without a large financial cost.
