Here’s a cool experiment from mobilewill about ambient temperature.
Every few weeks or so we make a trip to the water store to fill up our 3 gallon water container all while trying to avoid their delicious Santa Cruz ice cream. Upon arriving home, the container gets put into the refrigerator. At which point I started to wonder about the effect of the ambient temperature and how long it takes the water to reach equilibrium.

Waterproof DS18B20 Digital temperature sensor + extras: This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don’t get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them. Usable with 3.0-5.0V systems. Read more.
Food-Grade Heat Shrink – 3/8″ diameter 12″ long: We decided to stock this food-safe heat shrink specifically for people who were building beer-brewing or sous-vide projects using our waterproof DS18B20+ digital temperature sensors. This heat shrink is FDA Compliant for contact with food. The end of the sensor is stainless steel, but the jacketing is PVC, not good for dunking into your food or drink! But this heat shrink makes it easy – simply slip it on, allowing about 1 cm of the stainless steel sensor cap to be exposed, then heat it up to seal it on. The heat shrink will make a seal over the cap, so that no PVC touches your food project. Read more.
