To create an Arduino-based automatic smart water pump switching system using WiFi ESP, you'll need the following components:

1. Arduino board (e.g. Arduino Uno)

2. ESP8266 WiFi module (e.g., ESP-01)

3. Relay module

4. Water level sensor (e.g., float switch or moisture sensor)

5. Water pump

6. Power supply

7. Jumper wires

8. Breadboard or PCB (Printed Circuit Board)

Here's a step-by-step guide to creating the system:

1. Connect the ESP8266 WiFi module to the Arduino board. Connect the following pins:

   - ESP8266 VCC to Arduino 3.3V

   - ESP8266 GND to Arduino GND

   - ESP8266 TX to Arduino RX (via voltage divider circuit or logic level shifter)

   - ESP8266 RX to Arduino TX (via voltage divider circuit or logic level shifter)

   - ESP8266 CH_PD to Arduino 3.3V

   - ESP8266 GPIO0 to Arduino GND (for programming mode) - disconnect during normal operation

2. Connect the relay module to the Arduino board. Connect the following pins:

   - Relay VCC to Arduino 5V

   - Relay GND to Arduino GND

   - Relay IN1 to Arduino digital pin (e.g. pin 7)

3. Connect the water level sensor to the Arduino board. Connect the sensor output pin to an Arduino digital pin (e.g., pin 5).

4. Connect the water pump to the relay module. The pump should be connected to the normally open (NO) or common (COM) terminal of the relay.

5. Connect the power supply to the Arduino board and the relay module.

6. Install the necessary libraries for the ESP8266 and WiFi functionality. You can use the Arduino IDE's Library Manager to search and install the required libraries.

7. Write the Arduino code to control the system. Here's a sample code to get you started.

8. Upload the code to the Arduino board using the Arduino IDE.

9. Power up the system and ensure that the Arduino board is connected to your WiFi network.

Note: above the code is just a basic example to get you started.
