: Cold storage temperature is in practical applications an important indicator, for which I designed and developed this single-chip circuit test system, so that it can be refrigerated in the freezer temperature circuit testing and treatment. The system consists of AT89C51 single-chip temperature sensor and temperature data acquisition system using PC, the RS 232 serial port for serial data communications, the use of LabVIEW Virtual Instrument software PC serial communication procedures and procedures for front panel preparation. Experiments show the system to test the effect of making good.
