Design and Implementation of Multi-Channel Wireless Temperature Detection System
The wireless temperature detection system has a strong practical value in the civil market,industri-al scene,etc.A multi-channel wireless temperature detection system based on single-chip microcomputer is designed and implemented.The system includes the upper computer system and the lower computer system.The main control chips of both are STC51 single chip microcomputer,and the wireless communication uses ZigBee module for wireless data transmission and reception.The upper computer system mainly includes the minimum system,ZigBee module,LCD display module,LED over-temperature alarm module and USB mod-ule.The lower computer system has multiple nodes,and each node mainly includes the minimum system,Zig-Bee module and DS18B20 temperature module.Through the design of hardware and software and the estab-lishment of the platform,the temperature system is tested and debugged.Through the test,the system can col-lect and display multi-channel temperature data in real time through wireless form,with the function of over-temperature alarm and good stability.
