Systematic and rigorous monitoring of critical equipment is the cornerstone of any successful preventive management system in the industrial environment. Recent developments in cost-effective wireless sensor network (WSN) technologies promising a wider and more sustainable deployment of distributed sensing and processing infrastructure. In this research work, it is mainly focused on the electrical monitoring parameter and enable remote switching devices for optimal power management systems using ZigBee. This paper proposes a digital system for electrical system parameters such as voltage and current using ZigBee-based wireless sensor networks (WSNs). The main feature of ZigBee protocol, to act as a communicable medium between transmitter and receiver modules, which is suitable for the industrial environment. © Published under licence by IOP Publishing Ltd.
