WiFi module in the smart home application
The advantages of WiFi solutions are mature technology, individually designed to access the public network, and relatively low cost. The disadvantage is that the power consumption of WiFi devices is too large to meet the demand for power supply, wireless modules companies and the number of accesses is relatively limited, so that the home router can only access 32-64 devices.
Complex networking is not possible and the coverage capacity is severely limited by router deployment. WiFi solutions have a great advantage in the initial stage of the Internet of Things. A single module can rely on a router to access the Internet.
The advantages are obvious. Although the number of accesses is small, IoT and smart home applications are not widespread. It can also meet most of the needs.
Bluetooth module in the smart home application
Bluetooth solution has the advantages of low power consumption and simple interaction with cell phones. At present, the advantage of Bluetooth is power consumption, easy to interact with the cell phone, the disadvantage is that the device can not independently access the network.
With the popularity of Bluetooth 5.0 and Bluetooth mesh, Bluetooth module-based IoT applications are emerging like a spring. It is suitable for smart door lock, smart weight scale, smart toothbrush, mesh light control, smart lighting, smart building and other products that require power consumption and can be interacted with directly by cell phone.
From the development of the technology enterprise itself, BLE is very suitable for analyzing and connecting the sensor data in the smart home. Another more important reason is that Bluetooth application research has been everywhere.
