Temperature & Humidity Detector

Overview

DHT11 + ESP32 reads temperature and humidity and reports the values over serial or to a tiny dashboard.

How It Works

The DHT11 sensor uses a single data wire to transmit temperature (0–50 °C, ±2 °C accuracy) and relative humidity (20–90 %, ±5 % accuracy) readings. The ESP32 reads these values using the Adafruit DHT library and displays them on the Serial Monitor or a simple web dashboard.
