list of sensors used in refrigerator

Smart home appliances are the most important part of the entire home system, through automatic interaction, automatic control, to establish a complete intelligent home system. The first step in this is to use sensors to accurately collect data, and then carry out intelligent calculation and processing. Under the wave of intellectualization, more and more household appliances have begun to integrate various types of sensors and increase the intelligent perception function, in order to cope with the market trend of intelligent and energy-saving home appliances.

As an important member of smart home appliances, smart refrigerator is one of the indispensable home appliances in modern families, and its temperature control plays a vital role in food preservation and storage. Most of the refrigerators on the market are equipped with multiple sensors, the following list of sensors used in refrigerator.

Temperature Sensors in Refrigerators

Typically, refrigerators are equipped with multiple temperature sensors to ensure precise temperature control in each zone. Different makes and models of refrigerators may have slightly different configurations, but typically, a standard household refrigerator requires at least three of the following sensors:


  1. Refrigeration compartment (freezer) sensor: the main cooling area in the refrigerator, used for storing vegetables, meat, dairy products and other foods. This sensor will usually be placed in the upper or middle position of the refrigeration chamber to monitor the temperature inside the freezer. By accurately controlling the temperature in the refrigeration room, it can effectively extend the freshness period of the food and ensure the freshness of the food.


  1. Freezer Sensor: The freezer compartment is one of the most important storage areas in the refrigerator, used to preserve frozen meat, seafood, ice cream and other foods. This sensor is usually installed on the side or roof of the freezer to monitor the temperature inside the freezer. By accurately controlling the temperature in the freezer, the quality of frozen food can be ensured and food spoilage due to temperature fluctuations can be avoided.


  1. External Environment Sensor: Some high-end refrigerators are also equipped with an external environment sensor, which is used to monitor changes in the temperature of the surrounding environment to help determine when to appropriately adjust the operation of the refrigeration system. The presence of such sensors enables the refrigerator to automatically adjust the operating state of the refrigeration system according to changes in the external environment, further improving the temperature control accuracy of the refrigerator.

Application of VOC Sensors in Refrigerators

Corruption of food, bacteria and microbial reproduction is often accompanied by the release of organic volatiles, and the VOC sensor in the freezer with the freezer air circulation system can effectively monitor organic volatiles in all corners of the refrigerator: such as odors, rotten eggs ammonia-like substances, nitrogen gases, sulfur, and other substances that are generated during the process of food decay.

The integration of sensor solutions and smart home appliances is the foreseeable direction of development of the home appliance industry in the future, in the ever-changing market demand, it is more necessary for the industry chain upstream and downstream to cooperate with each other, hand in hand, from the perspective of consumer demand, through the power of innovation to bring the incremental space for the product to add innovative features and emerging selling points.
