Design of Wireless Meteorological Data Transmission System Based on 51 SCM

For the needs of short range wireless automatic meteorological station detection data transmission, a wireless meteorological data transmission system is designed. The system consists of transmitter and receiver, based on the 51SCM and NRF905 radio frequency control chip, and it has good adaptability to different types of automated meteorological stations. The system makes it possible to transmit wirelessly, display, and storage meteorological data. As being tested, the system has reached the requirements of the design both in terms of environmental compatibility and transmission capacity. It runs stably and reliably. The development methods of the transmitter, mainly from aspects of working principle and composition of the system, the design of the hardware, the programming of SCM, and the testing of the system are introduced.
