Abstract: This research aims to explore the collaborative optimization mechanism of Blind Signal Separation (BSS) and sensor technology, as well as its application value in complex environments. By systematically reviewing the mathematical principles of core algorithms in BSS (such as ICA and PCA) and the design principles of sensor technology (miniaturization, low power consumption, and high sensitivity), a joint optimization strategy for data preprocessing and BSS is proposed to address the problems of multi-source signal interference and noise suppression. Combined with case studies in agricultural sensor networks, dynamic monitoring of MEMS devices, and remote medical care, the effectiveness of the integrated technology in monitoring agricultural environments, analyzing livestock behavior, and separating respiratory signals has been verified. The results show that BSS can significantly improve the accuracy and robustness of data acquisition in complex environments, while the miniaturization and intelligence of sensor technology provide hardware support for edge computing. The conclusion indicates that the combination of the two technologies not only promotes the development of precision agriculture and intelligent healthcare, but also provides a technical path for real-time monitoring in areas with weak infrastructure. Future research should further optimize the lightweighting of algorithms and the development of low-cost sensors.
