{"title":"Waterproof SMD DS18B20 Digital Temperature Sensor","handle":"waterproof-smd-ds18b20-digital-temperature-sensor","url":"/products/waterproof-smd-ds18b20-digital-temperature-sensor","description":"This waterproof DS18B20 digital temperature sensor delivers accurate readings over a simple 1-Wire interface, requiring just a single data pin on your microcontroller. The sealed probe and silicone lead wire make it ideal for measuring temperatures in wet environments, outdoors, or at a distance from your controller.\n\nEach sensor has a unique 64-bit serial code, allowing multiple DS18B20 sensors to share the same 1-Wire bus. This makes it straightforward to build distributed temperature monitoring systems using a single GPIO pin on an Arduino or Raspberry Pi.\n\nKey Features\n\n\nWaterproof Probe – Sealed stainless steel housing for wet and outdoor environments\n\n1-Wire Interface – Only one data pin required; multiple sensors can share the same bus\n\nConfigurable Resolution – 9 to 12-bit selectable precision\n\nWide Temperature Range – Measures from −55°C to +125°C (operating accuracy ±0.5°C from −10°C to +85°C)\n\nDigital Output – No signal degradation over long cable runs\n\nUnique 64-Bit ID – Each sensor individually addressable for multi-sensor setups\n\nSilicone Lead Wire – Heat-resistant cabling rated to 125°C\n\nWide Supply Voltage – 3V to 5.5V operation\n\n\nWiring\n\n\nRed – VCC (3–5.5V)\n\nBlack – GND\n\nBlue – DATA (1-Wire)\n\n\nIdeal For\n\nAquarium, pool, and water temperature monitoring\nWeather stations and outdoor environmental sensing\nHVAC and building climate control systems\nHomebrew and fermentation temperature tracking\nArduino and Raspberry Pi projects\n\n\nPackage Contents\n\n1× Waterproof SMD DS18B20 Digital Temperature Sensor\n\n\nResources\n\nDS18B20 Datasheet (PDF)\nOneWire Library for Arduino\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2507,"title":"Default Title","sku":"DF-SEN0511","price":11.66,"on_sale":false,"in_stock":true,"available_quantity":126,"option1":"Default Title"}]}
