Smart home is a system product concept, and sensors are the “bridges” that connect traditional home equipment such as doors, windows, and lights. Through a variety of sensor devices, the scene of the smart home is realized, and the user can truly enjoy the fun brought by the smart home. What kinds of sensors are commonly used in smart homes? Please follow the small series to find out more.

First, the infrared sensor

Infrared sensors are measurement systems that use infrared as a medium. They mainly work with the physical effects of infrared radiation interacting with matter. In the smart home industry, in most cases, the electrical and physical effects of this interaction are utilized to enable the opening and closing of electrical devices with infrared switches. Infrared sensors have played a huge role in the practice of the smart home industry. With the improvement of detection equipment and other technologies, it will have more performance and higher sensitivity in the future, and lay a solid foundation for higher intelligence foundation.

Application case:YET611 reflective infrared photoelectric sensor is a photoelectric sensor that installs a transmitter and receiver into the same device, installs a reflector in front of it, and uses photoelectric reflection to complete photoelectric control. It can be used to detect changes in ground shading and color, as well as to detect objects that are close.

Second, temperature and humidity sensor;

The temperature and humidity sensor can detect the temperature and humidity in the air through a certain detecting device, and convert it into an electrical signal or other required form for information output according to a certain rule. It is used in a wide range of applications, where temperature and humidity sensors are used wherever temperature changes and water vapor content in the gas are monitored. It is not only related to the quality of the home environment, but also closely linked to human health. It can be said to be a vital part of smart home.

Third, the current sensor;

The current sensor is a detecting device that can sense the current information to be measured, and can transform the information sensed by the detection into an electrical signal or other required form of information that meets a certain standard according to a certain rule. It automatically detects and displays current and has automatic protection and more advanced intelligent control in the event of a hazard such as overcurrent or overvoltage. This technology with sensing, sensing, and sensing protection has also been widely used in the smart home industry.

Fourth, the door magnetic sensor;

The door magnetic sensor can be used to detect whether doors, windows, drawers, etc. are illegally opened or moved. Such sensors are typically mounted on doors or windows, sensing the opening and closing of windows and doors, and other smart security products to prevent external intrusions. It consists of a magnetic body and a permanent magnet. After leaving a certain distance, the magnetic sensor will emit a radio signal to the system terminal.

Application case: The remote intelligent wireless door sensor uses the magnetic sensor, the opening and closing of the door and window, and it will push the alarm information to the owner through the APP. With a three-month sustainability and a ready-to-use installation, it can be a smart security product for travel.

Five, gas concentration sensor;

A gas sensor is a device that converts information such as the composition and concentration of a gas into information that can be utilized by personnel, instruments, computers, etc., and is also an important detection means for smart homes. In home life, flammable gases and polluting gases are important factors affecting people’s health. In the smart home, the gas concentration sensor can be used to analyze the dangerous gas, so that a targeted control strategy can be adopted. This is also an important link to maintain the safety of the family and eliminate the danger in the period when it does not occur.

Application case: The remote gas alarm LED shows the concentration of carbon monoxide, which is detected by the gas concentration sensor. It also supports live voice prompts, both Chinese and English. Once the concentration exceeds the set value, it will upload the alarm information in real time at the same time as the local sound and light alarm, and the intelligent valve will eliminate the danger in the unburned.

Sensors commonly used in the smart home industry are more miniaturized, integrated, high-precision and intelligent. With the integration and integration of various sensors, and the continuous integration of sensors and other disciplines, sensors that are more subtle, more precise, and more intelligent must will play a vital role in the future of the smart home!
