Every Device is assigned with a unique address
For the Device which we are using it address is 0x48H
Temp | Humidity | Gas | Flame
Common to all Sensors is 4 pinout
1. VCC - 3.3V
2. A0 - Analog out - ADC
3. GND - 0V
4. D0 - Digital Op

Analog - voltages - sinusoidal signals
0-3.3V -- 0 --32767
2^16 - 0 to 65535 ( 65535/2 = +-32767)
  
y= 2.5V - Temp_Volt
x =  32767 * Y/3300
  
Value[0] =x
y= x*3300/32767
