FEATURES

What Sets It Apart

🧠

ESP32 Controller

Dual-core 240 MHz microcontroller with WiFi and Bluetooth. Runs PID loops, serves the web dashboard, and pushes data to the app.

🌡️

BME280 Sensors

Precision temperature, humidity, and barometric pressure monitoring at 1-second intervals. Full environmental awareness.

💧

Automated Humidity

Piezo ultrasonic humidifier with PID control maintains your target humidity ±2%. Set it and forget it.

🌀

Active FAE

PWM-controlled fan provides precise fresh air exchange. Automatically adjusts based on CO₂ buildup patterns.

📶

WiFi Dashboard

Built-in web server serves a real-time dashboard on your local network. No cloud account required — your data stays yours.

🔮

UV-C + LED Array

Same UV-C sterilization as The Void plus full RGB lighting — all software-controllable with scheduling and automation.
