Abstract

This article mainly illustrate how the P89V51RD2 SCM (Single-Chip Microcomputer) works. As the master control MCU, this type of SCM can make LCD(Liquid crystal display) screen show the temperature, humidity and light intensity from all different paths. We use 4*4 keyboard buttons type in message to control the device. Meanwhile, the master control and subordinate control use cluster communication, which makes it possible to enhance the reliability of data transmission. The detecting system we researched, can make the device detect the temperature, humidity and light intensity. Moreover, it also has other functions, such as data transmission, alarm in both sound and light, long distance alert and so forth.
