The default setting of the registers produces the 85, which is what you get if you read the sensor too soon after a reset. There is no adhesive holding the sensor itself to the PCB it is installed on. However, they were only using the integer part of the 12 bit register, and I wanted all of the information, as the temperature variations in cave system is often only fractions of a degree C. I found a floating point capturedemonstrated over at theBildr forum. How do you determine which module is ideal for the task at hand? Video: In the video, I have burnt a match stick to make temperature change around the sensor, but that is actually NOT necessary. Unfortunately, the majority of sensor modules arent waterproof or water-resistant. Due to its simple wiring, you can easily incorporate it into existing systems. #include It's basically a band of rubber that gets warm when electricity is passed through, and it's used on carboys and kegs for initial fermentation stages in wine or beer making.
