Step 1: Interfacing PIR Sensor With Ethernet Shield

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.
