A modular wireless sensor platform and its applications

In this paper, we propose a modular wireless sensor platform that consists of sensor modules. Each sensor module is a part of sensor system and in charge of one job in the system, such as computation, communication, output or sensing. Users can stack multiple modules together to build a unique sensor platform. Since users are able to easily replace one module with others, the proposed platform is highly extendable and reusable. Besides, we also design different kinds of mounts, so that sensors can be mounted on objects. This is especially helpful for some moving sensing applications such as attitude monitoring. To demonstrate the proposed platform, we show an alcohol detection application in the paper. The results show that the proposed platform is suitable for academic researches and industrial prototype verification.
