If you are familiar with our product, you will find there is waterproof temperature sensor named DS18B20. This waterproof temperature sensor kit is using the same probe——DS18B20 probe AS . It contains a probe with a resister module. So it is easy to connect on the Arduino board. 

The DS18B20 temperature sensor 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. Compatible with 3.0-5.5V systems.
