An ESP32-based gauge to monitor real-time car data via OBD2 serial connection.
Monitor live vehicle data from an OBD2 port using ESP32 hardware.
A low-cost, open-source solution to display car engine and sensor information.
A customizable gauge interface compatible with Arduino and PlatformIO.
ESP32-Serial-OBD2-Gauge-Catalyst enables users to build a simple, custom gauge displaying live vehicle data such as engine status and sensor readings using an ESP32 microcontroller and OBD2 serial interface. It supports Arduino and PlatformIO environments and uses LovyanGFX and LVGL libraries for clear visual output. This project is ideal for car owners and hobbyists seeking an easy-to-use, low-cost car data monitor without complex tools.
