This project uses an ESP32 microcontroller to scan for nearby Wi-Fi networks and display their SSID, signal strength (RSSI), and encryption status in the Serial Monitor.

• The ESP32 is set to station mode and scans for nearby 2.4GHz Wi-Fi networks.
• For each network found, it prints:
  • Network name (SSID)
  • Signal strength in dBm
  • Whether it is open or secured

• ESP32 DevKit v1
• USB connection to PC
• No external components required

1. Upload the WiFiScanner.ino sketch to your ESP32 using the Arduino IDE.
2. Open the Serial Monitor (baud rate 115200).
3. Every 10 seconds, a fresh scan of Wi-Fi networks will be displayed.

• ESP32 development using Arduino IDE
• Working with the WiFi.h library
• Serial communication
• Embedded system debugging and project documentation
