In the near future, homes without smart home systems will be as unpopular as homes that cannot be accessed today. Therefore, home intelligence will be the general trend. In this context, a convenient and stable smart home control device is essential. This paper has conducted in-depth research on the implementation of smart home control devices. Working principle: The working principle of the device is divided into four parts: remote control module, main controller, slave controller and control circuit. The remote computer and the mobile phone communicate with the main controller having the Windows CE platform through the Internet network and the GPRS network, respectively. The main controller and the slave controller are respectively connected to the Bluetooth module through the serial port, and communicate through Bluetooth transmission. The controller is directly connected to the control circuit, and the home appliance is controlled by the control circuit, as shown in the figure about the design of the wireless transceiver module circuit of the nRF0433.
