Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C - the limit of the sensor itself.

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.
