This kit lets you build a full climate monitoring and control station that maintains the ideal 12–14°C and 60–70% humidity your collection demands. Use the waterproof DS18B20 probe to monitor liquid temperature directly inside a representative bottle, while the DHT22 tracks ambient humidity and air temperature. The Arduino Uno runs a PID algorithm to switch a 5V relay — driving a heat mat or small cooler — keeping the cellar within a fraction of your target setpoint.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou will assemble and program a standalone climate monitor with a crisp OLED readout, microSD data logging with timestamps from the DS3231 real-time clock, and a relay output that regulates an external thermal device.
