**Circuit Connections:**

1. First of all place the Arduino Ethernet shield on the top of Arduino Board.

2. Connect the PIR sensor Signal pin to the digital pin 2 on the Arduino Ethernet shield using male to female connecting wire.

3. Take one male to male wire, connect one terminal of wire to the +5V of Arduino Ethernet Shield and other terminal of the wire on the Breadboard.

4. Take a male to female wire, connect 1 terminal where 5V pin of the Arduino is connected on the breadboard and the other terminal of the wire to the Vcc pin of PIR Sensor.

5. Take a male to female wire, connect 1 terminal to the GND pin of the Arduino Ethernet Shield and the other terminal of the wire to the GND pin of PIR Sensor.

## **Step 2: Interfacing Flame Sensor With Ethernet Shield**

**Circuit Connections:**

1. Connect the Flame Sensor D0 pin to the digital pin 3 on the Arduino Ethernet shield using male to female connecting wire.

2. Take a male to female wire, connect 1 terminal where 5V pin of the Arduino is connected on the breadboard and the other terminal of the wire to the VCC pin of Flame Sensor.

3. Take a male to female wire, connect 1 terminal to the GND pin of the Arduino Ethernet Shield and the other terminal of the wire to the GND pin of Flame Sensor.

## **Step 3: Interfacing Gas Sensor With Ethernet Shield**

1. Connect the Gas Sensor A0 pin to the Analog pin A0 on the Arduino Ethernet shield using male to female connecting wire.

2. Take a male to female wire, connect 1 terminal where you connected 5v pin of the Arduino on the breadboard and the other terminal of the wire to the Vcc pin of Gas Sensor.

3. Take a male to female wire, connect 1 terminal to the GND pin of your Arduino Ethernet Shield and the other terminal of the wire to the GND pin of Gas Sensor.
