Description: This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit (configurable) temperature readings over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor.
Dimensions: Probe is 7mm in diameter and roughly 26mm long. Overall length (including wire) is 6 feet.

Easy to connect got it working in less than 30 minutes.
These temperature sensors are very easy to hook up, and the measurements they give are accurate.
This is a great encapsulation of the DS18B20. We would buy it in the thousands if we could get a data sheet for it for UL. I have been told there is no data sheet available so we will have to use another device.
I have tested them with my RaspberryPi and work great!
Makes it super easy to measure temperature.. 1 wire bus is sweet too..
I used to think that this was too expensive until I realized how long it makes me to make them myself and now think it is well worth the price.
Easy to connect and very sturdy. Keep in mind you have to allow for the thermal characteristics of the plastic coating. Very flexible cable
