| Abstract: | In order to measure the moisture content of grain ,a capacitive type grain moisture tester based on MCU is designed .The hardware stucture is based on 555 oscillation circuit system and ATMEGA128 is selected as the major controlling chip .The result is displayed on 12864 LCD panel .The experimental results show that it can test the grain whose moisture content is between 13% ~25% .The tester works fast ,the result of the measurement is precise ,and it can adapt to different environment .Through the new method ,an accurate and high speed online measurement scheme was put forward . |
