Abstract

AbstractThis paper is for monitoring the speed, torque and protection of three phase induction motor from overload by implementing ZigBee based wireless sensor network. The design of the system maintains security, provides high reliability and also protect from many types of faults. The system has transmitter and receiver section which are controlled by PIC16F877A microcontroller. The communication between those sections are made by ZigBee transmitter and receiver section. The parameters such as voltage, current, speed and torque of induction motor were monitored. The monitored values are displayed in PC and as SMS in mobile through GSM technology. If overload condition occurs, relay driver circuit will open and makes the motor to turn OFF. Thus input values are maintained within the limit and speed of the motor will be in a controlled manner.KeywordsGSM technologyInduction motorOverload protectionSpeed monitoringWSN (wireless sensor networks)ZigBee transmitter and receiver
