With the development of science and technology and the advent of the 5G era, the concept of smart home and the Internet of Everything has penetrated into people’s daily life.

When many people hear about smart home, it is App control, curtain, lighting control. In fact, the current smart home can be very cool and practical. Of course, this requires professional design planning and customized implementation. What is a smart home?

What are the common sensors in smart homes, and what are their specific characteristics?

Smart home is also known as smart home. It is called “Smart Home” in foreign countries. It is based on the residence and integrates security monitoring, home appliance control, lighting control, background music, and voice control. Technologies such as automatic control technology and audio and video technology connect and centrally manage equipment related to home life intelligently, providing a more convenient, comfortable, safe, and energy-saving home living environment. Bring people a comfortable, high-quality and high-security life.

The so-called intelligence is reflected in the functions of automatic identification, automatic adjustment and automatic control. Simply put, it can also be remotely controlled through a mobile phone. Integrate and unify the facilities related to home life to build a convenient, comfortable, enjoyable, advanced, safe and healthy home environment.

And these smart homes are inseparable from an important accessory, that is, sensors.

The development and application of sensing technology have given objects a sense of touch, taste and smell, making them slowly come alive. This aspect is particularly evident in the smart home. The smart home system consists of sensors, actuators, control centers, communication networks and other parts. Various types of data of the indoor environment are obtained through various types of sensors, which are currently used more in the home. There are several types of sensors:

Temperature Sensor

The temperature sensor can ensure a constant room temperature in the smart home, and is an indispensable part of the smart home. In application, the temperature sensor can adjust the temperature according to seasonal changes or user needs.

What are the common sensors in smart homes, and what are their specific characteristics?

In the measurement of temperature, the temperature information can be collected through the temperature sensor. In modern smart homes, the temperature sensor usually selected must have the characteristics of stability and strong performance. In application, the digital signal can be converted into an electrical signal. The control of the computer system transmits the temperature information to the computer system, and then transmits it to the air conditioner through the central control system to realize the temperature control of the smart home. The Korean Samyoung anti-high humidity temperature and humidity sensor module provided by Gongcai.com replaces HM1500LF – HCPV-201H-11 is an accurate and reliable humidity measurement sensor module (HCPV-201 can also measure temperature). The sensor outputs a temperature-compensated humidity value via a linear voltage and can be connected directly to a microcomputer with an ADC input. The temperature output (only for HCPV-201) outputs the resistance value directly from the NTC thermistor, which can be directly connected to a microcomputer through the ADC input. Great for smart home use.

Image Sensor

In the smart home, the image sensor is also one of the important application components. Mainly because in modern construction, it is necessary to use monitoring equipment to achieve internal monitoring and monitoring of the surrounding areas of the house. In traditional monitoring methods, cameras are mainly used for monitoring, and information cannot be transmitted to users. Destruction will cause the user to bear greater losses. In the smart home system, through the monitoring of the PC, the information can be sent to the user’s mobile phone or computer to realize remote monitoring. In the smart monitoring, the image sensor can be used for photoelectric conversion, which is mainly composed of CCD and CMOS sensors. composition, through which digital cameras can be made to achieve full control over the smart home.

photoelectric sensor

In the traditional way of life, when people use water, power and light sources, they all need to manually set switches to complete. In smart homes, photoelectric sensors can achieve comprehensive control of smart homes. Automatic lighting can be designed by using photoresist, and convenient lighting for home can be realized through infrared sensing system without manual control. In addition, in the use of photoelectric sensors, infrared sensors can be used to control various conditions such as faucets, thermometers, humidity, etc., which can save corresponding resources and enhance the user’s enjoyment.

air sensor

The air sensor can monitor the monitored environment in real time for the user. Once the safety index is exceeded, the air purification equipment in the home can be triggered to purify the air and create a healthy air environment for the family. Air sensors can be embedded in various instrumentation or environmental improvement equipment related to the concentration of suspended particulate matter in the air to monitor air quality in real time.

For indoor air quality monitoring, the editor believes that the air quality sensor imported from Japan has high sensitivity to extremely weak air pollution gases (focusing on cigarette smoke). Like hydrogen or carbon monoxide present in cigarette smoke, this air quality sensor detects several ppm hydrogen. Due to the miniaturization of TGS2600, the heater current only needs 42mA, and the shell adopts standard TO-5 metal package.
