Design of Indoor Temperature and Humidity Detection System Based on MCU
Abstract:In order to detection and control the indoor temperature and humidity accurately and convenient, this article designs a indoor temperature and humidity detecting system with the 51 MCU as the control center, it uses SHT11 as information acquisition chip. The system uses SHT11 to collect temperature and humidity infomation,after AT89C51 MCU's treatment, LM016L can display the values. Also, the system can judge the real-time temperature and humidity values is OK or not. Then, the MCU can start the temperature and humidity controller, to make the temperature and humidity constantly.
Key Words : MCU AT89C51; SHT11 sensor; Temperature and humidity detection
