Wireless Sensor Nodes Optimized for Industrial Soldering Equipment

Abstract

To improve process stability, safety, performance and traceability for industrial machinery, the number of sensors has doubled in the last 10 years. Nevertheless, the evaluation of new or additional sensors is a constant task to improve the industrial machinery. In this context, there are two challenges: Firstly, the location must be determined, where the sensor should be located, on the other hand, the number of sensors used must be determined. It would be a tremendous improvement in terms of time and cost if a so-called wireless sensor node (WSN)could be used to test and implement these sensors. This paper shows the approach chosen for designing a WSN and the underlying technology. In addition, two experimental findings with this WSN are shown here. One with a temperature sensor and one with a residual oxygen sensor. The WSN will be optimized in a way to use the same sensors as used in an industrial soldering equipment in terms of temperature and sensor output.
