The design of the multi-locations wireless monitoring system based on ARM

In order to solve the problem of temperature monitoring location being difficult to monitor in more remote and dispersed geographical location, design a wireless monitoring system. It adopts 32-bit ARM controller LPC2114, uses AT commands and GSM public network SMS(Short Message Service) platform to control SMS module TC35i in the form of short message to transmit data, and it's receiving circuit displays monitoring data to achieve real-time monitoring of multiple monitoring locations, it's PC receives data, and completes the backup and processing of historical monitoring data. The System has the characteristics of low power consumption, high speed, simple circuit, and reliable data transmission. We make a little improvements, it can be applied to a variety of situation which need remote monitoring.
