Abstract

Wireless sensor networks are nowadays used in many industrial and automotive applications for distributed sensing and instrumentation. This paper presents the design of a dependable wireless sensor node for the application in automotive engine test beds. The sensor node is autonomously powered by means of a solar cell harvester module, which allows for the continuous operation of the sensor even in periods of low ambient light conditions. The measurement module features a Pt1000 based low power evaluation circuitry for temperature monitoring and a circuitry to determine the available input power for energy budget estimation. Experimental results obtained under laboratory conditions and in an automotive testbed are presented to demonstrate the applicability of proposed design.
