A method to monitoring the torque and efficiency in induction motor in real time by employing wireless sensor networks (WSNs). In Industries most of the mechanical works are done by motors among them 90% are induction motors. A controller unit (stellaries) is employed for acquiring electrical signals from the motor in a non invasive manner, and then performing local processing for torque and efficiency estimation. These values are calculated by the controller unit which are transmitted to a monitoring unit through a WiFi based WSN. At the base unit, various motors can be monitored in real time.
