[0012] The following content is a further detailed description of the shelf life prediction indicator of the present invention in conjunction with the accompanying drawings.
[0013] The shelf life prediction indicator of chilled fresh pork, the schematic diagram of its components includes an ultra-low power consumption microprocessor module (MSP430F1XX), a temperature sensor module (DS18B20), a single-key button module (reset, menu, jump, ok, ) , buzzer alarm module (shelf life alarm), liquid crystal display module (LM6059BCW), data storage module (AT24V64), calendar clock module (DS1302), serial communication module (RS232 communication protocol) and power processing module (5V Li battery) etc.; Among them, the temperature alarm function is all realized by software.
[0014] First, the temperature sensor module collects the real-time temperature of the surface of chilled fresh pork at a preset time point, and the microprocessor selects a rule in the shelf-life prediction rul...
