Design of intelligent rapid moisture meter based on microwave and halogen

Moisture content is one of the main grain storage quality indicators, is the basis for settled price Linking of the grain distribution, its fast and accurate determination is of great significance. This paper presents a fast, accurate and intelligent moisture meter, the system uses the microwave, halogen tubes as an energy source and makes DSP microcontroller as the controlling center, it has pressure transmitter, precision amplifier, 24-bit A/D converter, LCD monitor, you can quickly determine the weight of moisture in grain, moisture content, unit conversion can communicate with the computer through the RS232, realizing of human-computer communication, the system is easy to be operated with high precision, speed and so on.
