WebSerial is a Serial Monitor for ESP8266 & ESP32 Microcontrollers that can be accessed remotely via a web browser. Webpage is stored in program memory of the microcontroller.

Preview

Upgrade to Pro

Checkout the Pro version of the WebSerial library which comes with enhanced & snappy UI, along with 'clear' & 'lock scroll' buttons on the monitor interface. Best of all, it's only 10KB in size compared to 50KB of regular WebSerial.

Documentation

WebSerial is very similar to the default Serial Monitor Library of Arduino.

Please see Demo examples for better understanding on how to setup WebSerial for your Project: Click Here

WebSerial has 2 main functions:

• print
• println

print - simply prints the data sent over WebSerial without any newline character.

println - prints the data sent over WebSerial with a newline character.

Both functions support the following datatypes: String, const char, char, int, uint8_t, uint16_t, uint32_t, double, float.

To Access Webserial: Go to <IP Address>/webserial in your browser ( where <IP Address> is the IP of your ESP).
