How to Add and Simulate Gas Sensor in Proteus 8 | DC Voltmeter

Today, I will share how to add and simulate a gas sensor in Proteus 8 software. Gas sensors are used to detect and identify different gasses in the atmosphere. Eight types of gas sensors (MQ-2, MQ-3, MQ-4, MQ-5, MQ-6, MQ-7, MQ-8, and MQ-9) are available in this library.

1. TEP
   
   

Components:

1. Gas sensor
2. Logic state
3. DC voltmeter
   
   

Steps (Add Library)

1. Download the gas sensor library file at TheEngineeringProjects.com or click the link HERE. The download link will appear after 20 seconds.
   
   
2. Open the zip file and go to the folder Proteus Library Files. You will find three files on the downloaded zip file named:
   -GasSensorTEP.LIB
   -GasSensorTEP.IDX
   -GasSensorTEP.HEX
   
   
   
   
   
3. Extract these three files to the Proteus libraries folder (C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\DATA\LIBRARY).

   
   

Steps (Gas Sensor):

1. Open your Proteus software and add LOGICSTATE and all Gas Sensor components to the workspace.
   
   
   
   
   
2. Wiring components:
   
   -Connect VCC, OUT, GND of GAS SENSOR to the POWER, DC VOLTMETER through GROUND and GROUND.
   -Connect TestPin of GAS SENSOR to the LOGICSTATE.
   -Repeat the same step for other types of the GAS SENSOR.
   
   
   
   
   
3. Double click the gas sensor and click the folder icon in the Program File box. Go to Local Disk (C:) > Program Files (x86) > Labcenter Electronics > Proteus 8 Professional > DATA > LIBRARY > GasSensorTEP.HEX > Open > OK. Repeat the same step for other types of the GAS SENSOR.
   
   
   
   
   
4. Start the simulation. If the logic state is HIGH, then the OUT pin gives 5V output (HIGH).
   
   
   
   
   
5. If the logic state is LOW, then the OUT pin gives 0V output (LOW).
