Smart home is too expensive? Teach you how to DIY

Smart home networking is a development trend. Based on a comprehensive wireless MCU hardware platform, with a software development kit (SDK), it constitutes a comprehensive, complete and flexible and easy-to-use core resource. With the help of the development platform, innovative IoT products can be easily launched , To form an intelligent solution close to life.

When it comes to the unpredictable Internet of Things (IoT), the most grounded thing is that smart homes connect to the Internet. Household appliances are connected to the broadband network through the home gateway and sent to the cloud for information exchange and communication, which can realize identification, positioning, tracking, and remote management and control. The smart home networking system may include an embedded microcontroller (MCU), wireless connection, software platform, and application software APP. This article introduces a set of lively home networking solutions that cross the threshold of conceptualization and difficulty in landing, into reality, within reach.

System composition

In a typical application scenario, the home appliance networking system is composed of a microcontroller, a gateway, controlled items, and access control equipment. Isolated objects (refrigerators, air conditioners, cars, meters, etc.) are connected to the network world and can communicate with each other to form an intelligent network. Users can realize information collection, analysis and intelligent management of controlled objects through a tablet or mobile phone, and they can also go online for remote operation.

As can be seen from the above figure, the home automation system integrates embedded microcontroller technology, wireless connection, and access network. Apps software enables users to discover the devices at home, set them up, or create an action to control them. Remote control allows you to “discover, manage, and control” wherever you go without losing contact with your home. For example, while traveling, you can still monitor the safety environment of the house and adjust the indoor temperature of the house. The single chip of the microcontroller includes the wireless connection function, classified according to different wireless connection protocols, and can form WiFi, Bluetooth (Bluetooth), Zigbee and other series.

The key components

Microcontroller is a key component of home intelligence. MCU and Wi-Fi are the two most basic elements. Take a Wi-Fi microcontroller as an example. It is a single-chip SoC with a built-in full-featured microcontroller and supports 802.11n Wi-Fi.
