Creating a README.md file for an ESP32 project that involves controlling an LED is a great way to provide comprehensive documentation for users or developers who might work on or with your project.

This repository demonstrates how to implement motion detection using a PIR sensor with an LED and serial output across multiple platforms like Arduino Uno, ESP32, Raspberry Pi Pico, and STM32 Nucleo.

The Air Quality Sensor is powered by an ESP32-S3 microcontroller and uses a Plantower PMS7003 particulate matter sensor module to measure air quality. It looks like a small, black disk with AQI (air ...
