3rd International Conference on Mechanical Engineering and Intelligent Systems (ICMEIS 2015) Multifunctional Room Controller Design Tang Lili1, a, Huang Wei2, b 1Department of Computer Information Engineering, Zhixing College of Hubei University, Wuhan, 430011, China 2System Design Institute of Hubei Aerospace Technology Academy, Wuhan, 430040, China aemail: toney2001@126.com, bemail:jijunhuang@126.com Keywords: environmental monitoring; MCU AT89S52; digital sensor Abstract. This paper is mainly to study the working state of a certain space appliance through the MCU and the circuit. The main core of the design is composed by the control core microcontroller AT89S52, digital sensor, LCD FM12864M-12L and some other peripheral circuits. This paper mainly introduces the performance, inner structure, input and output structure of the AT89S52. It shows the driving mode of the DS1302, the DS18B20, the DHT11, and digital sensors such as the pyroelectric infrared, which are all the products of the DALLAS company. This design depends on the collections of the various environmental indicators by all the sensors mentioned above and its sending the collected data to the MCU. The MCU will set up the system parameter through the keys according to the various environmental indicators and the user, driving relay and a buzzer to control the operation of each electrical appliance and give the alarm. It finally designs human-computer interactive multifunctional controller interface based on LCD FM12864M-12L. Introduction With the development of electronic technology, the function of todays electronic products is increasingly various and the sales price is lower, so its access to peoples home
