DFRobot Gravity: Waterproof DS18B20 Water Temperature Sensor Kit 6A 125V AC Each relay can be loaded:Waterproof DS18B20 temperature sensor and for Arduino's combination can be used in many places,such as soil temperature detection, hot water tank temperature control, etc., but waterproof DS18B20 temperature sensor must be connected to a pull resistance to use, for this purpose we design the Plugable Terminal converter. Plugable Terminal digital adapter export increased pull up resistor,use the jumper cap switch, the waterproof DS18B20 temperature
