Appliances Bring New Markets to Sensors

As people pay more and more attention to the concept of energy saving and environmental protection, major manufacturers in household appliances also pay great attention to the control of energy efficiency. Energy-saving storms have already begun in the market, so sensors play a decisive role. In the "12th Five-Year Plan for the Development of China Household Appliance Industry" proposed by the China Household Electrical Appliances Association, the household appliances industry will be given prominence in energy conservation and emission reduction. The first is the air-conditioning industry, we can see that now all manufacturers have introduced inverter air conditioner as the main brand, which is a trend in the development of the air-conditioning industry.

In this energy-saving storm, the sensor is an indispensable component. As an awareness component of the home appliance control system, the importance is self-evident. Air conditioners use temperature sensors to sense the ambient temperature in the room and then take appropriate control Solutions. In traditional air conditioners, most of the temperature sensors only need 3, and now the frequency conversion air conditioner increases to 5-8. The same is true for the refrigerator industry, and the number of sensors is correspondingly increased. This brings new opportunities to the sensor market. .

The commonly used sensors in household appliances include temperature sensors, gas sensors, light sensors, ultrasonic sensors, and infrared sensors. The correct selection and use of home appliance sensors not only brings convenience to life, but also avoids accidents such as fire and damage. Many sensor companies are seizing this new market. Modern sensors equipped with intelligent control systems have also expanded the market of home appliance manufacturers and made its brand successful. Like current inverter air conditioners, they have become the product of choice for residents. In the latest energy-saving and emission-reduction regulations issued by the European Union, it was found that using new sensors to control burners became the first choice for many heating equipment manufacturers to upgrade their products. The use of sensors to monitor combustion also mainly reflects the following three methods:

First, the temperature, the flow rate, and the combustible gas composition are measured before the gas and air are mixed and burned to calculate the calorific value of the appliance and the required air supply.

Second, detect possible reaction areas. The number of ions and the number of some uncharged radicals can give the number of products as the reaction takes place. For example, if you know the volume fraction of oxygen, you might infer whether it is the adjustment of gas or air supply.

Third, the combustion state is determined by detecting the amount of carbon dioxide, carbon monoxide and nitriding gases in the exhaust gas. That is, the relationship between probe changes and combustion characteristics is selected, and a reliable control system is established. In addition, the following points need to be taken into account when choosing the right sensor: low cost, high reliability, long-term stability and high sensitivity.

In addition, various types of sensors are also indispensable in the home Internet of Things, which is another market for sensor manufacturers. The home appliance industry has achieved a growth in the sensor market, and sensors have also promoted the prosperity of the home appliance market. They have promoted each other and developed together.
