Research on Intelligent Measurement and Control System of Warehouse Temperature and Humidity

In order to accelerate the process of unmanned management of temperature and humidity control in a specific environment, a measurement and control system based on STC89C52 single-chip microcomputer, SHT10 sensor and relay is designed. The system uses a single-chip microcomputer to control the working status of the sensor, collect the temperature and humidity signals output by the sensor's own A/D, and display the measured value. When the measured value is inconsistent with the set value, the relay module is started to heat or cool the environment, or humidify or dry, until it is consistent with the set value. It is proved by experiments that the system has realized the predetermined function. Through software compensation, the accuracy of temperature measurement can reach 0.1°C and the accuracy of humidity measurement can reach 0.1%RH. When the measured value is inconsistent with the set value, the system can start the relay to work and issue an alarm, which is reliable.
