Abstract
Modern crop science and production required the real-time temperature monitoring of greenhouses and the improvment of the accuracy and efficiency of temperature measurement and control.An embedded microprocessor AT91SAM7X256 was used as the embedded systems collecting CPU of the temperature remote monitoring and control platform,transmitted distributed temperature data through nodes by the CAN bus,and monitored remote temperature through Web.Its temperature measurement accuracy was less than 0.5 ℃.The system has good practical value and application prospect.
