Application research of pressure sensing system in agriculture based on SCM

Pressure sensing technology is used to pressure environment monitoring in agriculture, a basic pressure sensing system is designed. The pressure signal acquisited by pressure sensor in agricultural environment is converted into sensor amplified output voltage, and then changed into pressure digital signal by A/D converter. Finally the agricultural pressure data manipulated and analyzed by SCM program is sent to upper computer with a serial port, in this way the system can detect and monitor pressure parameter of agriculture environment in real time. This system is simple, reliable, economic, expandability and has a great agricultural application value.
