Abstract: In this paper, a method for measuring the moisture content of grain has been presented based on single chip microcomputer and capacitive sensor. The working principle of measuring moisture content is introduced and a concentric cylinder type of capacitive sensor is designed, the signal processing circuits of system are described in details. System is tested in practice and discussions are made on the various factors affecting the capacitive measuring of grain moisture based on the practical experiments, experiment results showed that the system has high measuring accuracy and good controlling capacity.
Keywords: Dielectric Properties, Moisture Content, Capacitive Sensor, Signal Conditioning.
Scope of the Article: Measurement & Performance Analysis
