In this paper, aims at monitoring parameter of induction motor like current, voltage, torque and efficiency in real time by employing embedded system with wireless sensor networks. An embedded system is employed for acquiring electrical signals from the motor in a noninvasive manner, and then performing local processing for torque and efficiency estimation. The values calculated by the embedded system are transmitted to a monitoring unit through an IEEE 802.15.4-based Wireless Sensor Network (WSN). At the base unit, various motors can be monitored in real time. The Air Gap Torque (AGT) method is used to find out the torque and efficiency in induction motor.
