| Abstract: | Cold storage is an important part of modern agriculture, and the temperature and humidity are the important parameters of each warehouse must be considered. The multi-point temperature and humidity data acquisition controller is designed in the paper with a MCU. The controller is Used AT89S52 as the core chip, measured by the digital sensor SHTT5 in temperature and humidity, expended external circuit, realized multi-point temperature, humidity display, parameter setting, real-time monitoring and network transmission. This paper details the hardware principle diagram, and introduces the software flow. Tests show that the design is correct, safe and reliable. |
