Take temperature readings from a distance, or underwater, using this Waterproof DS18B20 Digital Temperature Sensor. It's got a 90cm (0.9m) cable with a stainless steel, PVC coated probe at the end. You'll be able to use it with any 3V-5V system, and take temperature readings with an accuracy of 9-12 Bits (configurable in code). The best part is that it's digital, meaning you won't suffer any signal degradation over the longer distance.
This sensor is simple, you've got 3 wires (Power, Ground and Data). You simply need to connect the data pin to an input pin on your micro-controller (Arduino, etc) and the power and ground to power and ground!
You'll also need to connect a resistor between power and signal wires, as shown in the circuit diagram on the Sensor's wiki page.
You can simply use the One-wire library for any Arduino projects (See the examples below for more in-depth information). We've even made our own tutorial on using this sensor with a Raspberry Pi! As always, we're full time maker's with experience using this gear and we're here to help. Make a post in our forum to get more information on anything maker related.
