Handy 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. Original ds18b20 temperature sensor probe used chips.
