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.
