In order to achieve the intelligent infrared control of common household appliances, we choose to use smartphone instead of traditional infrared remote control. we use the Internet resources to design system, and select Baidu Cloud Development Platform to deploy the project and install the database; Infrared terminal controller is designed to use four 90 degrees infrared lightemitting diodes with a wavelength of 940 nm,plus 2.4 GHz PCB antenna, and set TLN13UA06 outside of the microcontroller development platform to achieve converting between WiFi and serial; CC3200 offers WiFi, using 802.11n protocol stack to achieve WiFi communication with the maximum transmission rate of 600mbps; Eclipse development platform is using to develop mobile control terminal APP interface, and Web Service calls for cloud data with request method. We test it on an air conditioner with many times, and find out the system design is stable, and the experimental results are consistent with the preset function.
