Design and application of multi-channel data acquisition system based on short-range wireless communication technology

摘要

In view of some environmental data acquisition devices have single sensor type, lack of stability, high cost, large energy consumption, awkward to use, this article designs a multi-channel data acquisition system with core chips of C8051F310 and CC1100, based on short-range wireless communication technology. It has the advantages of supporting multiple types of sensors, strong stability, low power, low cost, and easy to use. Including data acquisition principle of the different types of sensor, communication principle of node-to-node and node-to-PC are described in detail. It achieves data acquisition from five-channel different types of sensors, short-distance point-to-point wireless transmission, and real-time data display, warning, node setting on monitoring side.
