ESP32 WiFi initialization disrupting GPIO analog reading

I'm programming an ESP32 through Arduino IDE, and I'm having a strange issue with Arduino's WiFi library. When I connect to my WiFi network, it forces reading of a particular pin (Pin 2) to 4095. With the line of code connecting to WiFi commented out, I get a correct reading on a sensor I have connected to that pin, but with it included it's stuck at 4095. This also happens when the microcontroller is disconnected from the rest of the circuit. With the line commented out I get a white noise reading, but the 4095 reading with the line included. Here's the code:

//Libraries 
#include <WiFi.h>

//Wi-Fi Connection Parameters
const char* ssid     = "REMOVED";
const char* password = "REMOVED";

const int sensePin = 2;

//Initialize WiFi Server
WiFiServer server(80);

void setup() {
  pinMode(sensePin, INPUT);
  int senseOut = 0;

  Serial.begin(115200);

  // Connect to WiFi network
  WiFi.begin(ssid, password); //THIS LINE CAUSES 4095 READING
}

void loop() {
  TestSensor();
}

void TestSensor()
{
  for (int i = 0; i < 100; i++)
  {
  senseOut = analogRead(sensePin);
  Serial.println(senseOut);
  delay(100);
  }
}

Example of white noise reading:

Any ideas what could be causing this? Thank you.

Solution

You need to use another analog input.

These pins do not support analog input when WiFi is in use: 00, 02, 04, 12, 13, 14, 15, 25, 26,

These ones do: 32, 33, 34, 35, 36, 39, Use one of these last 6 to connect your sensor.
