Microcontroller & GSM Based industrial faults monitoring system

Abstract 

    The aim of this project is to monitor industrial faults like three phase voltages up and down, Fire or smoke, and presence of persons to the prohibited areas. In this monitoring system the device consists of GSM modem, microcontroller, relays, display and sensors like PIR sensor, smoke sensor, potential transformers etc. when somebody enters to the prohibited area the PIR sensor connected will detect the presence of person, and it will give an interrupt to the microcontroller. Smoke sensor (Passive infra red sensor) is used to detect the presence of smoke ultimately fire is detected. The microcontroller continuously checks the conditions of the phases connected to the loads. Under the phase failure condition of any phase, this system detects and automatically switches off the three phase supply, LCD display is connected to the system to display the status of the system. On any interrupt by sensors SMS is sent to the in charge person to inform the status of industry and all orders are accepted by SMS through GSM module connected to the microcontroller.
