LIU Yi;WANG Shi-yu;HE Wei;XU Jian;ZHANG Jian-qiang;ZHAO Guo-jun;YANG Biao;Hubei institute for nationalities;  
Using STC89C52 microcontroller,temperature humidity sensor DHT11,GSM module,DS1302 clock chip,WT588 D voice module,design a kind of has the function of clock display and alarm and temperature and humidity tester with voice function.After system boot,DHT11 temperature humidity sensor to collect temperature humidity value,and put the data into single chip microcomputer for processing get Celsius temperature and relative humidity value,will be output to 12804 LCD module for display,and through the keys to control the speech function,system can customize the alarm temperature,automatic alarm when the temperature reaches a certain value.And long distance transmission by GSM module real-time data to the user's phone,the system performance indicators: temperature measurement range 0~50℃,1℃ accuracy;Humidity measurement range 20% RH to 90%RH, precision1%RH.This instrument has high stability,accuracy and practicability.
