STC89C52 microcontroller, this design with Sensiron company developed the first DHT series of intelligent humidity / temperature sensor, coupled with photoresistor to form the basis of the measurement and control system. And based on a design example: with the DHT sensor and photosensitive resistance in combination with an external AD to achieve the environmental temperature and humidity measurement, display and control system design methods, SCM source code and application design. This article is designed by a design example the principle and application of to understand collecting temperature and humidity and light intensity, and the design with the upper and lower limits of temperature and humidity adjustment function When the alarm information generated by setting a good GSM program, will send alarm information to the specified phone. Keywords: temperature and humidity measurement and control, DHT11, STC89C52 microcontroller, GSM 目录 1引言 5 1.1课题的开发背景和意义 5 1.2 湿度控制系统的研究方向以及特点 5 1.3课题设计的实现的三大功能： 6 1.3.1 测量温湿度 6 1.3.2检测烟雾气体浓度 6 1.3.3 GSM远程报警 7 2 系统硬件电路的设计 7 2.1单片机最小系统的
