The system composed by the data acquisition module and display module. Data acquisition module which uses a microcontroller STC89C52RC as the core structural, It ensure the system on-site collection of temperature and humidity signals. The usefulness of the entire system to provide a solid communications security.That such communication has become the development direction of industrial communications. This design mainly introduces temperature and humidity acquisition system uses STC89C52RC as the control core through SHT71 digital temperature and humidity sensors , real-time acquisition of the storehouse environment temperature and humidity . The use of liquid crystal display LCD display data 1602. To achieve the purpose of real-time monitoring of temperature and humidity. This system has a readable, high stability, reaction speed, measured values exact characteristic.
