Key technologies for smart home access to the Internet of Things
When it comes to the inscrutable Internet of Things (IoT), the most grounded air is the smart home access to the Internet. The home appliance connects to the broadband network through the home gateway, and is sent to the cloud for information exchange and communication, which can realize identification, positioning, tracking and remote control. The smart home networking system may include an embedded microcontroller (MCU), a wireless connection, a software platform, and an application software APP. This article introduces a set of living home networking solutions that span the threshold of conceptualization and landing, and come into reality, at your fingertips.
one. System composition
In a typical application scenario, a home appliance networking system consists of a microcontroller, a gateway, a controlled item, and an access control device. Isolated items (refrigerators, air conditioners, cars, meters, etc.) access the network world and can communicate with each other to form an intelligent network. The user can realize the information collection analysis and intelligent management of the controlled object through the tablet or the mobile phone, and can also go online for remote operation.

As can be seen from the above figure, the home automation system integrates embedded microcontroller technology, wireless connectivity, and access network. Apps software enables users to discover devices at home, set them up, or create an action to control them.
Remote control allows you to "discover, manage, and control" anytime, anywhere, no matter where you go. For example, if you are traveling, you can still monitor the safe environment of your home and adjust the indoor temperature of your home.
The microcontroller single chip includes wireless connection functions and is classified according to different wireless connection protocols to form WiFi, Bluetooth, Zigbee and other series.
