Wireless technology has gradually begun to go into the homes of ordinary people. In recent years, wireless data transmission technology using in largescale industrial production systems has been a big trend, while the rise of the Inter of Things also promote the widespread use of wireless data transmission technology. This thesis is based on the rise trend of the Inter of Things, design and manufacture the wireless data transmission module. This thesis mainly describes the design of wireless data transmission module for the Inter of Things and plete the module for debugging. This design uses a modular design way, pleted power supply module, GPRS wireless munication module, RS232/485 serial munication module and MCU module. In the thesis, each module is described in detailed and makes various points to pay attention to. In the designing process, through investigating the existing products on the market and pare different programs, this design took a variety of points to pay attention to and the functions to be achieved into account, considering the actual situation, and pleted the design of the module, meet the requirements of the desired design. In the application, with the subsequent upgrades and improvements, this design is believed to bee an official product onto the market and will be well weled in the flourish of the Inter of Things. The purpose of this thesis is twofold, first is to present the design and operating principle of wireless data transmission module and the other is to debug and investigate its performance. The result of test and analysis the module is recorded in detail in the thesis.
