*Wokwi Simulation *

1. Create a new project in Wokwi.
2. Add the following components:
- Arduino Uno or ESP32 Dev Board.
  - Soil Moisture Sensor.
  - DHT11 Temperature and Humidity Sensor.
-  oid setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  Serial.println("Hello, ESP32!");
}
