In order to realize the collection and monitoring of remote environmental information, the system uses discrete component to design wireless transceiver module for bidirectional data transmission with the use of C8051F020 microcontroller as control and data processing chip and realizes multi-computer communication for the mutual transmission of environmental data through the corresponding encoding and decoding algorithm. System hardware and software design and implementation are explained in details and its flow chart are also presented. (C) 2017 The Authors. Published by Elsevier Ltd.
