Bluetooth Based Industrial Security System Electronics Engineering Final Year Project

This project includes Bluetooth (HC-05) module, which is connected to Arduino through UART interface. Bluetooth module works with 2.4Ghz frequency. It has-80dBm sensitivity. DHT11 and fire sensors connected to Arduino digital pins. DC fan controlled by relay which is connected to Arduino digital pin.

WORKING:

In this project industrial parameters can be monitored through Bluetooth app. Temperature, Humidity and fire can be monitored. This system has two mode, manual and auto. We can set modes in Bluetooth App. If mode in auto then DC fan will be ON when fire will ON. If mode in manual then DC fan will be from Bluetooth app. We can monitor three sensor values in Bluetooth APP. Also sensor values displayed on 16X2 LCD display.
