Design of Rechargeable and Integrated Grain Water Content Meter
Detecting grain’ s moisture is of great significance for grain resources’ efficient utilization.In the grain consu-ming market, grain products’ quality and processing condition are both influenced by moisture content, which is a main assessment criteria and also an important factor.So, in order to detect moisture content conveniently and in low cost, the moisture content meter which was rechargeable and integrated was designed with AT89 S52 single-chip microcomputer as the controller, two-parallel plate as the capacitance sensor and DS18B20 as the digital temperature sensor to detect ca-pacitance and temperature of the grain.Meanwhile, based on the established model describing relationship between grain ’s moisture content and capacitance as well as temperature , moisture content of grain could be well measured with the assistance of the lower computer software system developed by Keil C language for controlling SCM ( Single Chip Mi-cyoco) procedure, the PC monitor software programmed by JAVA language to receive and display test data from the lower computer in real-time.
