DFRobot Gravity: Waterproof DS18B20 Sensor Kit

This waterproof temperature sensor kit use DS18B20 probe AS . It contains a probe with a resistor 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.

If you want to make a simple water purifier, we recommend buying together with Gravity: Analog TDS Sensor/Meter for Arduino
