The Food Warehouse Temperature Measurement System Design Based on Microcontroller

Abstract:

The thesis takes the microcontroller STC89C52 as the core control element. It selects the platinum thermal resistance PT100 sensor as a temperature detection element, and we use it to collect the temperature of the food warehouse act in concert with the Amplifier circuit and the ADC0809 analog-to-digital converter chip in real time. The collected temperature is displayed on the LCD1602 display module. According to the result of the comparison of the collected temperature values and setting values, this system gives off the corresponding alarm signal , and then starts the heating device or cooling device to achieve the purpose of controlling the temperature inside the warehouse, in this way, we can ensure the temperature of the warehouse in an appropriate range.
