Temperature LED Indicator
Sensors · Board: ESP32 · Day 43 of 100
A DHT22 on the ESP32 maps temperature to LED colors. At-a-glance climate feedback.
How it works
The DHT22's temperature reading is sorted into bands — cool, comfortable, warm, hot — and each band lights a different LED color. You read the room's climate at a glance without parsing a single digit.
What you'll learn
- Sensor-to-color mapping
- Temperature banding
- Ambient information display
- DHT22 vs DHT11 accuracy
