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.

Great 1-wire sensor kit, easy to setup and use, having low latency at around 15ms. Random addresses means having many sensors at the same 1-wire bus is no problem. Recommended.

Excellent waterproof temperature sensor kit! The Gravity: DS18B20 is accurate, reliable, and easy to use with Arduino, ESP32, or Raspberry Pi. I tested it in an IoT project for liquid temperature monitoring, and it performed perfectly even in outdoor or humid environments. The stainless steel probe and sealed cable ensure full waterproof protection. Using the One-Wire interface makes wiring simple and allows multiple sensors on the same bus. The readings are stable and precise with fast response time. Ideal for weather stations, aquariums, or industrial applications. Great quality and documentation from DFRobot — highly recommended!
