In this project, we proposed a system where you can easily monitor and control the different parameters using sensors. In this we used a Raspberry Pi and Arduino Nano. Blynk is used as an open source IOT platform through which data is send from the sensors to the cloud. Here we used five sensors for the monitoring the Industrial System. In which all component plays crucial role & have individual responsibilities. Since we used five sensors out of which three sensors (Temperature, Smoke and Light) are analog sensors and rest of the two sensors are digital (Fire and IR) where these sensors are interfaced to the ADC Input Channels. Temperature sensor which is used to monitor the temperature inside the industry, whenever it raises above the threshold value of 50, the module sends a mobile notification from Blynk, displays the current temperature reading value on the Dashboard and LCD, turns ON Buzzer and Common LED and also powers ON the Fan through relay. Smoke sensor which is used to monitor the smoke inside the industry, whenever it raises above the threshold value of 50, the module sends a mobile notification from Blynk, displays the current smoke reading value on the Dashboard and LCD, turns ON Buzzer and Common LED. Fire Sensor is used to detect flame inside the industry, whenever decreases below the threshold value of 25, the module sends a mobile notification from Blynk, displays the current temperature reading value on the Dashboard and LCD, turns ON Buzzer and Common LED. Light Sensor is used to monitor the light intensity inside the industry, whenever it decreases below the threshold value of 25,the module sends a mobile notification from Blynk , displays the current temperature reading value on the Dashboard and LCD, turns ON Buzzer and Common LED and also powers ON the Bulb through relay.IR Sensor is used for motion detection Sensor i.e. whenever a person enters into Restricted Areas, whenever decreases below the threshold value of 25,the module sends a mobile notification from Blynk , displays the current temperature reading value on the Dashboard ,turns ON Buzzer and Common LED.
In Power Line Communication the purpose of implementation is to transfer the data from one industry to another industry through the existing power lines where both are present near to each other. In this we have considered Light Sensor as a parameter to transfer the data from Sub Industry to the Main Industry i.e. whenever the Light senor value crosses a threshold value 50, a message signal is send from Raspberry Pi to PLC TX through Serial Communication. A local carrier signal is internally generated in both PLC TX and PLC RX having carrier frequency of 125KHz.Now message signal is modulated with the carrier signal (FSK Modulation) and the modulated signal that is obtained is now passed from PLC TX AC Line to the PLC RX AC Line. Here AC Line acts as a medium for the modulated signal to pass from TX to RX. Now the modulated signal that is received at the PLC RX is demodulated using the local carrier signal (FSK Demodulation) and the message signal is now obtained back, this message signal is passed to the Arduino Nano through Serial Communication. The message signal is now read on the serial monitor through a USB cable connected to Arduino Nano which also acts a power supply to PLC RX and Arduino Nano. Serial Monitor displays the message to the Main industry officials, whenever the Light value decreases below a threshold value and they can take necessary actions immediately.
