Abstract

In the field of embedded technology, advancements are taking place due to emerging technologies. Emphasizing the deployment of the on chip resources of ARM LPC 2378 microcontroller, an embedded system is designed to measure soil moisture. Recently, agriculturists are demanding high-tech instrumentation to monitor various parameters such as temperature, light intensity, humidity, gas concentration, concentration of fertilizers, pH, soil moisture, etc. Out of various soil parameters, the soil moisture is playing significant roles on the crop growth. Considering this demand, an embedded system is designed to measure soil moisture and the results are interpreted in this paper. The sensor, comprising two steel electrodes, is designed in the laboratory and implemented. The on chip ADC of LPC 2378 is deployed. In order to provide better isolation, signal conditioning stage is designed around the instrumentation amplifier AD620. The firmware is designed in embedded C using SCARM. For calibration of the system test bed is designed in the laboratory. The system is implemented for the measurement of soil moisture and the results obtained are discussed.

Keywords
