The application of sensors in the small appliance industry is wide and diverse, covering almost all types of small appliances. Here are some specific application examples:

1. Rice cookers: Sensors play a key role in rice cookers. They can detect the temperature and humidity during the cooking process, and adjust the heating power to achieve the state of keeping the rice warm by transmitting signals to the controller, making the rice taste more fragrant and sticky. At the same time, the sensor can also issue an alarm when the rice cooker encounters an abnormal situation to ensure safe use.
2. Coffee machine: Temperature sensors play an important role in coffee machines. They are used to monitor the temperature of coffee water to ensure that the coffee extraction temperature is in the optimal range to release the best flavor and aroma of coffee. In addition, sensors are also used to monitor the temperature of steam, control the quality and taste of milk foam, and monitor the temperature of the coffee machine itself to prevent malfunctions caused by overheating.
3. Washing machines: The application of sensors in washing machines makes the washing process more intelligent and energy-saving. Washing machines can monitor the weight, material and degree of dirtiness of clothes through sensors, and automatically adjust the water level, washing time and detergent dosage. This not only improves the washing effect, but also saves energy and water resources.
 4. Air purifier: Sensors can monitor indoor air quality, such as the concentration of harmful substances such as PM2.5 and formaldehyde. According to the monitoring results, the air purifier can automatically adjust the operating mode and wind speed to provide the best air purification effect.
5. Smart lighting: Sensors are used in smart lighting systems to sense ambient light and human activities, automatically adjust light brightness and color temperature, provide users with a comfortable lighting environment, and save energy.

In addition, sensors are also widely used in small household appliances such as fans, toasters, and microwave ovens to achieve temperature control, flow detection, safety protection and other functions. In general, the application of sensors in the small household appliance industry not only improves the intelligence level of products, but also improves user experience and energy saving effects.
