Gravity: Waterproof Temperature Sensor Kit, DS18B20 - 

KIT0021 is a gravity: waterproof DS18B20 temperature 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 12bit (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. Waterproof temperature sensor DS18B20 is widely used in many fields, such as soil temperature measurement, hot tank temperature control etc. It supports multipoint measurement. Typical applications include constant temperature control, industrial system, consumer electronics, thermistors, refrigerators, barns, tanks, telecommunication rooms, power communication rooms, cables etc.
