About 10 % of total industrial energy consumption in Europe is spent for generation of compressed air, which can be found in almost all manufacturing industries. Compressed air is very expensive energy source, thus big attention should be paid to the structure and condition of the compressed air system and to its energy consumption. Implementing energy saving measures with high monitoring level of compressed air system can significantly reduce factory energy consumption. Wireless Sensor Network (WSN) based monitoring solution for industrial pneumatic machines was developed. Sample tool kit system for production environment monitoring was also created. Monitoring of pneumatic system's condition by online wireless senor network allows forecasting technical, managerial and maintenance problems in larger supply chain.
