ESP32 Powers Automated Smart Terrarium System
On March 31, 2026, a maker published a step-by-step project for a fully automated smart terrarium built around an ESP32 that monitors and controls lighting, humidity, temperature, and soil moisture. The design uses DHT11, a soil moisture sensor, mist maker, fan, water pump, WS2812B LEDs, and a 3-channel relay, plus an on-device web dashboard and OLED status display. It implements hysteresis, fail-safe shutdowns, and manual/auto modes.
Key Points
- 1Implements ESP32 automation controlling lighting, humidity, temperature, and watering via sensors and relays
- 2Uses hysteresis and fail-safe shutdowns to prevent rapid relay switching and unsafe operations
- 3Provides replicable design with common components, OLED and web dashboard for easy extension
Scoring Rationale
Fresh, practical DIY guide with high actionability and clear component lists increases score. Limited novelty and single-author maker credibility reduce impact despite good documentation; published today so no freshness penalty.
