Abstract [en]

In recent years wireless sensor network (WSN) is introduced in the fresh food tracking area as a promising solution to monitor the food transportation process. The widely applications of WSN are demanding a Universal Sensor Interface (USI) that is able to support large numbers of sensors, including gas sensors, force sensors, temperature sensors, water quality sensors, etc. In this thesis, the Universal Sensor Interface (USI) based on Programmable System on Chip (PSoC) from Cypress is presented and discussed. Multiple sensor interfaces are implemented in PSoC therefore a "sensor interface design library" is established. The dynamic reconfiguration, which is a key feature of USI, is also demonstrated. It allows USI to support multiple sensors in a time division fashion by in-circuit and run-time reconfiguration. Part of the sensor interfaces are tested and evaluated, proving both the hardware and software design. Finally the conclusion is made and future work is discussed as a guidance of the follow up work.
