Abstract

The design of the hardware and software of a multifunctional agricultural meter is presented. Its controlling center is based on the new type Micro-controller AT89C52. In the A/D converting stage the V/F converter is used and the sensors, which are reliable, cheap and satisfactory to the degree of the accuracy, are used. Therefore the system has the features such as simpler interface, stronger anti-jamming, more adaptive distant transmission, better measurement accuracy and better control reliability. The system can be applied extensively in the agriculture.
