The system consists of input parameter such as USB camera, Metal detector, Fire sensor and LPG gas sensor, this parameter interface with controller ARM-11 (Raspberry pi). -The microcontroller also interfaces output side parameter such as LCD, Alarm, Indicating LEDs and Wi-Fi module.  The indicating LEDs are red and green colored, out of them green color led on if module or circuit is on and other red led on at the time of any predefined threshold value is greater than the threshold value. The USB camera is a compact digital camera you can hook up to controller to broadcast video images in real time. It captures light through a small lens at the front using a tiny grid of microscopic light detectors built in to an image sensing microchip. A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. If target found then alarm indicate them and that time red color LED is glow. A flame detector is a sensor designed to detect and respond to the presence of a flame or fire. It also set a predefined threshold value & it increases then alarm on and also red color LED glow. Similarly, LPG gas sensor are used to detect LPG of an concentration it also set predefined threshold value and it rises then indicate red color LED and alarm on. -This data display the controller at LCD display and any user send text SMS then it will be display on LCD via Wi-Fi module.


1.      Initialize the USB camera and camera port

2.      Initialize the metal detector and controller ADC pin

3.      Initialize the fire sensor and controller ADC pin

4.      Initialize the LPG sensor and controller ADC pin

5.      Initialize the buzzer and LCD display

6.      Initialize the Wi-Fi module

7.      Initialize the Controller input and capture pins

8.      Start Conversion of ADC

9.      Wait Still ADC conversion end

10.  Read the digital value from ADC

11.  Compare the ADC result with predefined threshold value

12.  If threshold value greater than threshold level then glow red LED and on alarm or buzzer

13.  This data is saves controller and display its LCD and also send text SMS of any user through Wi-Fi module and also display
