Study on a Wireless Temperature and Humidity Monitoring System for Workshop with Constant Temperature Based on SCM

Abstract

A wireless temperature and humidity monitoring system for workshop with constant temperature based on AT89C52 Single chip microcomputer and nRF905 wireless microchip is studied. The system is consists of base station and slave station. Base station is mainly consists of temperature acquisition module, humidity acquisition module, wireless communicating module and communicating testing module. Good communication protocols play an important role in ensuring the correct monitoring data. So the network topology, communication data form, ad hoc networks protocol, mac protocol and data link layer protocols are discussed for commutation protocol to host computer software. The cost of the system is low and it has a large function area and a good performance. It is able to provide messages of workshop with constant temperature for improving machining accuracy and prolonging the life of equipment in machine shop.
