The document discusses the development of an affordable wireless data logger for use in museum environments. It proposes using the Arduino open-source electronics prototyping platform to create a prototype data logger capable of logging temperature, humidity, and time. The document outlines the hardware and software requirements for the data logger and presents images of a prototype device created with the Arduino platform. It argues that open-source platforms like Arduino are well-suited for this application due to their low-cost, flexibility, and active developer community support.
