In the Internet of Things (loT) era, technology offers the ability to collect and understand information collected from the nature and environment around us. As an essential component of reliable sensing, sensors play a vital role in any IoT system. The point of departure for our work is the anticipated potential of an efficient, low-cost prototyping and testing platform for analog sensors. In this paper, we explore the fundamental building blocks of such a system: an accurate, configurable analog front end, a light-weight communication component, and efficient data-centric middleware, and a user-friendly web portal.
