Design of Wireless Environmental Monitoring Data Acquisition System Based on Cortex

Remote environmental monitoring often has the characteristics of monitoring points widely distributed, large numbers, long distance, individual collection points in remote areas, etc. In the past, the manner of remote environmental monitoring data acquisition that staff operate in person on the spot is extremely inconvenient. In order to solve the problems produced in the manner above, we design the Cortex-M3-based wireless environmental monitoring data acquisition system, which has the following excellent features: It adopts a high cost-performance chip based on Cortex-M3 core; Pre-terminal, integrated into a circuit board, has small volume, take up less space, and can work without any special requirements for the environment; System can automatically restart; Power supply designed for the system can reduce the interference on the circuit from external AC voltage, and lower the interference from high frequency entering through power supply; It can be applied to multi-channel data acquisition information monitoring system.
