Mainly consists of a power supply, a temperature detection circuit, a system control circuit , actuator, the temperature display circuit, alarm circuit and other parts, using DS18B20 temperature sensor detects the current temperature of cold storage through the STC89S52 controller and auxiliary circuit to calculate the output, and the LCD display the temperature value; if the measurement value is upper or lower limit value, the system will alarm, and at the same time to start or stop the actuator, making the temperature quickly reached the preset range. Keywords: IOT; Sensor; Temperature detection Introduction Cold storage is using cooling facilities to create the proper humidity and temperature conditions of warehouse, also known as cold storage, processing and storage of agricultural and livestock products. It can get rid of the influence of climate, prolong the period of storage preservation of agricultural and livestock products, in order to regulate market supply. At present, if you want to speed up the refrigerator industry to safe, normative, environmental protection, energy saving, convenient operation, simple structure of the direction of development, we must to improve the automatic management level of the cold storage and management to be further strengthened, and the operation cost is greatly cut down. This paper design temperature control system is a simple operation, and is low-cost, easy to run. This system is DS18B20 digital sensor to detect temperature, STC89S52 microcontroller to control the cold storage temperature, with temperature, alarm and control temperature and other functions.
