Sensors are the basis for smart home control systems to achieve control. With the development of technology, more and more sensors are used in smart home systems, such as washing machines, refrigerators, televisions, and microwave ovens. Here we introduce to you what sensors are used in smart home.
Introduction of sensors in smart home
Pressure Sensor
Pressure sensor is a kind of sensor most commonly used in industrial practice. Generally, the output of ordinary pressure sensor is an analog signal, and the analog signal means that the information parameter appears as a continuous signal within a given range. In smart homes, it is generally used for monitoring the amount of foam in washing machines and dryers.
Chemical sensor
Chemical sensor A device that senses various chemical substances and converts their concentrations into electrical signals for detection. In smart homes, it is generally used for water quality monitoring.
Photoelectric system
Optoelectronic system uses electronic methods to process and control optical information. It is a kind of optical radiation that is used to receive reflections from the target or its own radiation, and obtains required information or capabilities through transformation, processing, and control. , and perform the necessary processing optoelectronic devices. In the smart home, it is generally applied to monitor the turbidity of the washing machine, so that the number of washing cycles is in accordance with the actual needs.
Electromagnetic sensor
The electromagnetic sensor will measure the change of the magnetic flux induced in the conductor and convert it into a sensor whose output signal changes. In a smart home, it is generally used in a dishwasher to control the movement of the spray arm.
Non-contact detection system
Non-contact measurement refers to accurate measurement without touching the measured object. In smart homes, micro-machined thermocouple infrared sensors, which are commonly used for temperature control, can also be used in cookers, hair care appliances and toasters.
Flow Sensors
The flow sensor is a sensor that measures the flow of air drawn into the engine. In smart homes, it is generally used for the detection of air quality in electric fans and vacuum cleaners.
Smart multi-gas sensor
Smart sensors with microprocessors (MCUs) have the ability to collect, process, and exchange information, and are a combination of sensor integration and microprocessors. In smart homes, it is generally used for automatic cooking control.
Without sensor technology, there can be no smart home. It is with the rapid development of sensing technology that we will experience the charm of smart life. For example, when the room temperature is higher than 29 degrees, the air conditioner will be turned on automatically; when someone enters the kitchen, it will automatically turn on the lights; when the plants are short of water, they will be automatically watered. Of course, smart homes based on sensing technology can achieve far more than these. If you want to learn more about smart homes, leave a comment below the article!
