Problems solved by technology

Most of the smart thermostats on the market have rich functions. They use single-chip microcomputer as the central processing unit, and use thermistor or digital temperature integrated sensor to collect temperature. The temperature controllers include compressor control, multiple defrost control, various Fan control and other output control methods; the interface adopts LED digital tube or LCD screen, with indicator lights to indicate control and alarm status, and the display information is comprehensive and intuitive; these temperature controllers have comprehensive functions and can basically be used for routine use, but they are not suitable for use in Temperature control occasions that require network monitoring and use, and there is a lack of technology in cold storage and compressor protection
