DIY Arduino Aquarium Controller Pt3: Monitor Temperature with DS18B20

This covers Wiring, programing, and using the DS18b20 digital thermometers to monitor and log the temperature in your Reef aquarium
Part3 of my How-to series for Arduino Mega and Raspberry Pi based DIY Aquarium Controller.

note: library order can matter - the new DallasTemperature.h library broke the code - the fix was to load it BEFORE the OneWire.h library

Glad you enjoyed it!

This is awesome. Thank you for sharing. Whether thermal probes oxidize in seawater?

[@BlueBladeFish]

I have had them in the saltwater tank for several years now, no sign of oxidation or corrosion.
