Common IoT applications in smart home with four wireless modules

In the application of smart home, we can network various smart home wireless modules through Bluetooth modules, Wi-Fi modules, ZigBee modules,RS485 to TCP/IP converter and LoRa modules, and realize real-time interactive control through mobile APP, cloud platform or smart speakers. The application of wireless modules in smart homes makes our home life more comfortable, safe and worry-free, improves our overall living standards, and guarantees our quality of life. At present, there are hundreds of devices with wireless modules integrated in smart homes.

Smart door lock:

On the basis of the original access control system, a low-power Bluetooth transparent transmission module is added to realize the connection of mobile phone Bluetooth protocol. The smart phone can call the Bluetooth service through the APP, send instructions, and the smart access control lock receives the Bluetooth instructions, and then controls the switch of the smart access control lock.

Smart air conditioner:

The Wi-Fi module is integrated in the smart air conditioner, and the data such as the real-time temperature and working mode of the air conditioner can be uploaded to the remote server or background management system through the Wi-Fi router. We can read the data of the air conditioner in the background management system through the mobile phone APP. You can also send air conditioner control information to change the state of the air conditioner.

Adjust the air conditioner to the desired mode before we go home, instead of turning on the air conditioner after we go home, so that we can enjoy the appropriate temperature in time. The operation mode of the smart air conditioner has greatly improved our experience after combining the Wi-Fi module and the cloud platform.

Smart lighting:

In the application of smart lights, we can choose smart lights with integrated Wi-Fi modules. We can adjust the color temperature, strobe mode, working time and other parameters of the smart lights through the mobile APP. At the same time, we can also directly connect to the smart lights. The Wi-Fi module is directly controlled without the need for a router to upload and send data.

If it is a smart light with Bluetooth protocol or ZigBee communication protocol, our router can be replaced with a corresponding Bluetooth module or ZigBee gateway device, serial rs485 to ethernet converter and the data can be uploaded to the background management system through the gateway device, which can also realize remote control of household products. We can also combine Bluetooth smart speakers to control smart lights through voice.
