ABSTRACT

I

Single-chip technology has been greatly developed, single-chip measurement and control technology has been widely promoted and applications. Single-chip technology not only application In the factory, but also in the household appliances also there are a wide range of the applications. This new part of any microcontroller system test technology as the industrial control, the application of household appliances intelligent provides an effective test method. I believe that the the next there will be a good prospects.

This work is in accordance with the the characteristics of of the warehouse environment. The the theory of of the the application of single-chip technology and modern measurement the temperature and humidity and and so on environment, for the warehouse of the factor carried out automatically detected. To achieve the purpose of the alarm, to timely discover and solve problems. The present works joined the GSM module, the wide range of applications of GSM module. Be able to in a timely of the to send text messages notify the the people in charge of the warehouse and found that the abnormal problem of the warehouse temperature and humidity. Early detection can be early solution to minimize the loss.

The first chapter a brief introduction on the development and current status of the work of this paper to determine the direction of the design; second chapter introduces the system design requirements; Chapter III presents the system design; fourth chapter describes the hardware design of the system ; the fifth chapter is the design of the system software
