🌡️ Mastering the DHT11 Sensor with ESP32
In this video, we dive deep into how to use the DHT11 temperature and humidity sensor with the ESP32 step by step.
You'll learn everything — from hardware wiring to code implementation using ESP-IDF, and we’ll discuss the timing protocol, data reading, common issues, and how to get accurate results every time.
🎯 What You’ll Learn:
What is the DHT11 and how it works internally
How to connect it properly to your ESP32 (with pull-up resistor)
Understanding the single-wire communication protocol
Writing your own driver in ESP-IDF (no Arduino libraries!)
Debugging and fixing common reading errors
Displaying live readings on a simple web dashboard
Pro tips for stable and accurate measurements
💡 Whether you’re building an IoT weather station or learning embedded systems, this video will help you master the DHT11 from A to Z — in a simple, practical, and enjoyable way.
