Introduction
This waterproof temperature sensor kit features a DS18B20 probe with a resistor module. It includes a pluggable terminal adapter, making it easy to connect to the Arduino board without soldering.
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. It is compatible with 3.0-5.5V systems.
For simple water purifier projects, it is recommended to use this kit together with Gravity: Analog TDS Sensor/Meter for Arduino.
