Digitising statistics handling through hardware and mobile web technology

Abstract

Today mechanical tally counters are used to collect statistics. However, data stored in the mechanical counter is hard to overview and draw conclusions from. This thesis presents an approach which utilises a wireless low energy protocol to transfer the data of a mechanical counter to a smart phone and then to a server. The data stored in the server is distributed and displayed to the users of the service in a lucid and comprehensible manner. The goal is real-time communication and distribution of the data while optimising energy consumption, to the point where the battery of the tally counter can last several years. The focus of this thesis is evaluating the balance between energy conserving approaches and real-time communication. The thesis concludes that Bluetooth low energy is the best suited technology for the task. Among the approaches tried, its star topology gives good battery life, real-time communication and easy con guration.
