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.

Waterproof - Take the temperatures of liquids/moist environments with the stainless steel probe. It's shrouded in PVC plastic too, meaning it will hold it's own in temperatures up to 100 degrees Celsius.
Temperature - Usable from -55 degrees Celsius to 125 degrees Celsius. Accuracy of 0.5 degrees.
Digital - The digital interface used to relay the readings guarantees minimal signal degradation over the longer distances (90cm for this standard cable)
1-wire interface - You can have multiple DS18B20s connected to the same central micro-controller pin as each device has a unique identifier hard-coded in.
Long range - 1.5 meters of cable by default, but you can make it longer if needed
Maker friendly - The DS18B20 chip is able to be powered with 3v - 5.5v which is perfect for maker platforms .
HOOK-UP GUIDE
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 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.
