Abstract    With the development and progress of science and technology and economy,the modern environment monitoring equipment is becoming increasingly digitalized and intelligent。For the past several years,research on wireless sensor network technology has gradually become hotter and hotter in the field of industries and academics,and it has a very broad application prospects in the military and civil fields。Besides,as microelectronics technology,sensor technology,wireless communication technology and embedded computer technology develop and progress,wireless sensor network technology get to develop rapidly as a result。All of these have provided a more effective and efficient way for environment monitoring。In practical engineering exploitation and application,usually it is necessary to monitor a variety of parameters,such as temperature, humidity, light intensity, gas concentration,etc,in perse locations。Using the wireless environment monitoring device,we can be more effective and real-time in collection,transmission and display of these needed environmental parameters。

In order to realize the real-time monitoring of environmental parameters,the work presented in this paper focuses on designing a wireless environment monitoring device based on AT89C51 MCU。This device consists of a monitoring terminal and a detecting node。 The monitoring terminal is based on AT89C51 MCU as the central control system,and equipped with the  wireless transceiver module and the LCD module, etc。It can realize the function of wirelessly receiving and displaying the data sent over by  the detecting node。The detecting node is composed of AT89C51 MCU, the wireless transceiver module, the light,temperature and humidity sensor data acquisition module,etc,and it can realize the detection of the surrounding temperature,humidity and light information。 The wireless environment monitoring device designed in this project can accomplish accurate measurement and efficient transmission of environmental parameters in practical application,which embodies the advantages of wireless,digitalization and intellectualization of this device。
