Wireless temperature and humidity sensor Internet of Things is a new generation of information technology

The Internet of Things is a key link of the new generation of information technology, and also an important development stage in the information age and digital age. The Internet of Things technology is known as the third wave of the world’s information industry development after computers and the Internet. The core of IoT technology development is the innovation of user experience. With the continuous progress of IoT technology, its application in daily life is more and more extensive. In this context, the development of the Internet of Things has further driven the rapid growth of residential electronic integration industry and smart home industry. As the core technology support of smart home, the Internet of Things technology plays a pivotal role.
Advantages of IoT technology in smart home
The flexibility of traditional smart home is very poor, and its compatibility performance is also poor. With its complete system, the Internet of Things technology organically combines various household appliances through wireless, playing an incomparable advantage in smart home. Taking ZigBee as an example, ZigBee is safe and reliable in smart home with low cost. It can coordinate communication among thousands of free micro sensor units with high communication efficiency. From the technical perspective, ZigBee smart home has great integration, can seamlessly link with the cloud, and is convenient for management, traceability, timely perception and control. It will certainly be widely used in the field of Internet of Things smart home.
Technology of Internet of Things in Smart Home
Perception layer
Comprehensive perception is a feature of the Internet of Things technology, that is, using radio frequency identification (RFID), two-dimensional code, GPS, cameras, sensors and other sensing, capture and measurement technologies to collect and obtain information from the perceived objects anytime, anywhere. In smart home, the perception object is divided into the home environment people live in and people themselves. The eight subsystems in traditional smart home can be used as the executive devices of the perception layer. In addition, IoT smart home systems also apply many typical sensing technologies, such as wireless temperature and humidity sensors, wireless door magnets, window magnets, wireless gas leakage sensors, etc.
network layer
The network layer in the Internet of Things includes the integrated network formed by various communication networks and the Internet. In addition, it also includes the home Internet of Things management center, information center, cloud computing platform, expert system and other parts that can intelligently process massive information. In smart home, the network layer should not only have the ability of network operation, but also improve the ability of information operation, such as the application of databases. In the network layer, it is particularly important to deal with reliable transmission and intelligent processing.
application layer
The application layer is a solution set that combines the Internet of Things technology and smart home expertise to achieve intelligent home applications. The Internet of Things finally realizes the deep integration of information technology and traditional home through the application layer, which is mainly reflected in smart grid applications, home medical applications, multimedia entertainment applications, home security applications and home control applications. In addition, the application layer also provides a third-party excuse for home service providers to provide various services that are convenient for people’s lives.
Application of Internet of Things Technology in Smart Home
Wireless temperature and humidity sensor
Wireless temperature and humidity sensor is mainly used to detect indoor and outdoor temperature and humidity. Although most air conditioners have the temperature detection function, due to the volume limitation of the air conditioner, it can only detect the temperature near the air conditioner at the air outlet, which is also an important reason why many consumers feel that the temperature is inaccurate. With the wireless temperature and humidity detector, you can know the accurate indoor temperature and humidity accurately. Its practical significance lies in that when the indoor temperature is too high or too low, the air conditioner can be started in advance to adjust the temperature. The wireless temperature and humidity sensor is also of special significance for you to go out in the morning. When you stay in an air-conditioned room, you have no sense of the outdoor temperature. At this time, the temperature and humidity sensor installed outside the wall can play a role. It can tell you the current outdoor real-time temperature. You can decide your own clothes according to the accurate temperature, without the embarrassment of wearing more or less after going out.
Wireless infrared intrusion detector
The wireless infrared intrusion prevention detector is mainly used to prevent illegal intrusion. For example, when you press the wireless sleep button at the bedside, not only the light will be turned off, but also the wireless infrared intrusion prevention detector will start automatic defense. At this time, once someone invades, an alarm signal will be sent out and the set light in the intrusion area can be turned on automatically to scare off the intruders. Or when you leave home, it will automatically set up a defense. Once someone breaks in, it will automatically remind your phone through the wireless gateway and accept the alarm processing instructions sent by your phone.
Wireless air quality sensor
The wireless air quality sensor is mainly used to detect whether the air in the bedroom is turbid, which is very meaningful for you to go home to rest, especially for families with infants. It tells you whether the current indoor air affects your health by detecting the air quality, and can start relevant equipment to optimize the air quality through the wireless gateway.
Wireless doorbell
Wireless doorbell is very valuable for large families or villas. For safety reasons, most people will close the door when they sleep. At this time, when someone comes to visit and presses the doorbell, it is difficult to hear the bell in the room. This kind of wireless doorbell can transmit the ringing signal to the bedside light to remind you that someone is visiting. In addition, when there is no one at home, the doorbell will be sent to your mobile phone through the gateway, which is very important for you to understand the security status of your home and visit information.
Wireless door magnet and window magnet
Wireless door magnets and window magnets are mainly used to prevent intrusion. When you are at home, the door and window magnets will automatically be in the disarm state and will not trigger an alarm. When you leave home, the door and window magnets will automatically enter the arming state. Once someone opens the door or window, they will notify your mobile phone and send an alarm message. Compared with the traditional door and window magnets, the wireless door and window magnets do not need wiring and can be installed with batteries. The installation is very convenient. The installation process generally does not exceed 2 minutes. In addition, for families with a safe, this sensor can also detect and record the time when the safe is opened or closed each time, and notify the authorized mobile phone in a timely manner.
Wireless gas leak sensor
Wireless gas leakage sensor is mainly used to detect gas leakage in the home. It does not need wiring. Once there is gas leakage, it will send an alarm through the gateway and notify the authorized mobile phone.
Wireless radiation sensor, wireless air pollution sensor
Wireless radiation sensors and wireless air pollution sensors are of special significance to people who are sensitive to solar radiation. You can accurately know whether you need to take measures to prevent solar radiation or pollution and dust before going out.
The emergence of the Internet of Things has brought hope for smart home to thousands of households. Some domestic communities have established “cloud communities”, which have made a preliminary attempt at the Internet of Things technology in smart home. However, this is only a preliminary application. In the future, the Internet of Things will play an increasingly important role in smart home. Its powerful sensing technology will make smart home more “intelligent”, and even have some thinking functions of people. It will provide people with practical and sticky services, so that the smart home industry can develop faster.
