The security of grain has been focused on the topic of people＇ s lives, in the process of grain reserves, the monitor of grain＇s temperature and humidity as well as pests is an important measure to maintain grain＇s security. This paper designs a grain monitor system through the use of a Sub-G Hz band and CDMA technology, the system gets the internet and internet of things together, the collected data will be transmitted through the CDMA network to the remote PC, then PC accordingly analysis the data to monitor and control the grain＇s security.The system possesses a far transmission distance,low cost and low power, so it has a good prospect.
