Multi-layer sensing approach for environmental perception via a multi-functional sensor

Presents an environment perception approach based on a multi-layer sensing technique using one multi-functional sensor to measure temperature, humidity and brightness. It focuses on the processing of the multifunctional information in a multi-layer framework, which is more attractive in terms of both system simplicity and performance, and is proved to be effective to solve the problem of more than three quantities being reconstructed. A CdS and Fe₃O₄ material based multi-function sensor has been developed and the quantity creditability tactics for multi-layer data fusion has also been proposed for use
