Abstract
Wireless measurement systems will provide significant benefits to industrial applications, for production facilities as well as in mobile or R&D scenarios. However, in order to exploit the improvements by flexibility, scalability and easy reconfigurability brought by wireless sensor networks (WSN), industrial use cases often require a sustainable autonomous energy supply, while providing the reliability which is comparable with today's wired systems. In this work we introduce a sensor node implementation with a temperature measurement circuit design, optimized for low energy consumption, while providing industry-grade accuracy and resolution. A first implementation realizing the concept of a switched signal acquisition circuitry is discussed, demonstrating the impact of the energy harvesting and storage unit. In a second implementation, a coordinated signal conditioning and power management concept is introduced.
