Step-by-Step: Simulate IoT Circuits with Proteus

Let’s simulate a simple but common IoT circuit: Temperature Monitoring System using ESP8266 and DHT11 sensor in Proteus.

Step 1: Launch Proteus Software

• Open the Proteus simulation software.
• Click File → New Project.
• Name it something like IoT_ESP8266_DHT11.
• Proceed until you see the blank schematic design window.

Step 2: Add Components for IoT Circuit

Use the Component Mode (P) and search for:

• ESP8266 (Requires external library)
• DHT11 Sensor
• LCD 16x2
• Virtual Terminal
• Power supply, resistors, ground

For Proteus ESP8266 and DHT11 modules, install the relevant libraries.

Step 3: Connect Components

Make the following connections:

Step 4: Write Arduino Code and Export HEX

Use the Arduino IDE for code development:

#include <DHT.h>

#define DHTPIN 2
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);

void setup() {
  Serial.begin(9600);
  dht.begin();
}

void loop() {
  float t = dht.readTemperature();
  float h = dht.readHumidity();
  Serial.print("Temp: ");
  Serial.print(t);
  Serial.print(" °C  Humidity: ");
  Serial.print(h);
  Serial.println(" %");
  delay(2000);
}

• Go to Sketch → Export Compiled Binary
• Locate the .hex file in your Arduino sketch folder

Step 5: Upload HEX in Proteus Simulation

• Double-click ESP8266 in the circuit
• Under Program File, browse to your .hex file
• Set Clock Frequency: 16 MHz

Step 6: Start the Simulation

Click ▶ Play in the Proteus toolbar.

• The Virtual Terminal will display real-time temperature and humidity values.
• LCD will show output if properly programmed.

Make sure your baud rate in the code (9600) matches the virtual terminal setting.

 

Step 7: Run the Simulation

• Press Play ▶️ button.

• Watch real-time data in Virtual Terminal.

• If code is correct, you’ll see temperature and humidity readings.

Note: If nothing shows, recheck pin connections and baud rate (should match Serial.begin(9600)).

Proteus Online Simulation – Is It Available?

As of 2025, Proteus online or Proteus software online simulation is not officially supported. You must install the desktop version to use full IoT simulation capabilities.

Some online tools like Wokwi, Tinkercad Circuits, or EasyEDA support Arduino online simulation, but not Proteus-level advanced modules like ESP8266 or GSM.

Installing Proteus ESP8266 and DHT11 Libraries

How to Install Custom IoT Libraries in Proteus:

1. Download .LIB, .IDX, and .HEX files for:
   • ESP8266, DHT11, GSM, LCD
2. Copy them to this directory:

   C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY
   

3. Restart Proteus.
4. Search for the components again via “P” search box.
