Abstract—A design of wireless sensor networks for mechanical condition monitoring system (WSN-MCM) is presented in this paper. The main purpose of this work is to develop a WSN system for mechanical condition monitoring as the existing mature wireless sensor network nodes are not suitable for the long-time monitoring of mechanical equipment due to their short working life and low acquisition accuracy. In order to realize the function of long-term working of the sensor node, we designed an energy harvesting board of the node to harvest the energy and transferred energy with high efficiency . Meanwhile, the node has the function of high-accuracy acquisition of analog signals and can access of various low-frequency and high-frequency sensors. The experiment and stimulated results demonstrate that the wireless sensor network system designed is suitable for mechanical condition monitoring.
