First, we need to understand what smart appliances are. Smart appliances are home appliance products formed by introducing microprocessors, sensor technology, and network communication technology. They can automatically perceive the state of the residential space, the appliance itself, and service status, while automatically controlling and receiving commands from users locally or remotely. As components of a smart home, smart appliances can interconnect with other appliances and facilities to form a system that realizes smart home functions.

So, what are the common sensors found in smart appliances?

(1) Pressure sensors are used for water level control, such as monitoring water levels in washing machines and dishwashers.

(2) Photoelectric systems are used to detect the turbidity in appliances like washing machines.

(3) Chemical sensors are used for water quality monitoring, including solubility, pH, turbidity, etc.

(4) Electromagnetic sensors are used in dishwashers to control the movement of spray arms.

(5) Thermocouple infrared sensors are used in cookers, ovens, and hair care appliances.

(6) Flow sensors can be used to measure air quality in vacuum cleaners.

(7) Smart multi-gas sensors can be used for automatic baking control.

(8) Reed switch sensing technology is used in many appliances for water level detection, dishwasher spray arm control, washing machine drum position detection, and door safety detection.

In the future, smart appliances will become an indispensable part of smart homes, and their large-scale adoption will continue to expand.
