{"title":"Waterproof DS18B20 Sensor Kit","handle":"waterproof-ds18b20-sensor-kit","url":"/products/waterproof-ds18b20-sensor-kit","description":"A waterproof DS18B20 digital temperature sensor kit with everything you need to connect to an Arduino. The stainless steel probe measures temperatures from -55°C to +125°C over a 1-Wire interface, requiring just one digital pin for communication. Multiple sensors can share the same data pin thanks to unique 64-bit IDs.\n\nThe kit includes a terminal sensor adapter for easy plug-and-play connection to Arduino — no breadboard wiring required.\n\nKey Features\n\n\nWaterproof Probe – Stainless steel housing for immersion in liquids\n\n1-Wire Interface – Only one digital pin needed for data\n\nMulti-Sensor Support – Multiple probes can share a single data pin\n\nWide Temperature Range – -55°C to +125°C (-67°F to +257°F)\n\nConfigurable Resolution – 9 to 12-bit temperature readings\n\nTerminal Adapter Included – Easy connection to Arduino without soldering\n\n\nSpecifications\n\n\nSensor – DS18B20\n\nOperating Voltage – 3.0–5.5V\n\nAccuracy – ±0.5°C (-10°C to +85°C)\n\nTemperature Range – -55°C to +125°C\n\nResolution – 9 to 12-bit (configurable)\n\nQuery Time – <750 ms\n\nProbe Dimensions – 6 mm diameter × 35 mm long (stainless steel)\n\nCable Length – 90 cm\n\nCable Diameter – 4 mm\n\n\nWiring\n\n\nType A: Red = VCC, Black = GND, Yellow = DATA\n\nType B: Red = VCC, Yellow = GND, Green = DATA\n\n\nPackage Contents\n\n1× Waterproof DS18B20 temperature probe\n1× Terminal sensor adapter (DFR0055)\n1× Digital sensor cable\n\n\nIdeal For\n\nWater temperature monitoring (aquariums, pools, brewing)\nEnvironmental and weather station projects\nArduino and Raspberry Pi temperature logging\nIndustrial and outdoor temperature sensing\n\n\nResources\n\nDFRobot Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12835,"title":"Default Title","sku":"DF-KIT0021","price":13.41,"on_sale":false,"in_stock":true,"available_quantity":985,"option1":"Default Title"}]}
