ESP32 Weather Sensor Starter

Goal

Use an ESP32 to read a compatible digital temperature/humidity sensor and display values over the serial monitor.

Requirements

ESP32 development board, compatible sensor module, USB data cable and a computer.

Steps

  1. Install the correct ESP32 board package in your development environment.
  2. Check the sensor datasheet for supply voltage, GPIO wiring and required library.
  3. Connect power and ground carefully, and select a suitable data GPIO.
  4. Load an example for your sensor model, then verify readings in the serial monitor.

Ensure the connected sensor signal levels are safe for ESP32 3.3 V GPIOs.
