{"title":"Temperature Sensor - High Temperature, Waterproof (DS18B20)","handle":"temperature-sensor-high-temperature-waterproof-ds18b20","url":"/products/temperature-sensor-high-temperature-waterproof-ds18b20","description":"A sealed, waterproof DS18B20 digital temperature probe for precise measurements in wet or harsh environments. The sensor communicates over a 1-Wire interface, requiring just one data pin (plus ground) to connect to your microcontroller. It can even be parasitically powered from the data line.\n\nEach DS18B20 has a unique silicon serial number, so multiple probes can share a single 1-Wire bus — ideal for multi-point temperature monitoring in HVAC systems, equipment, and process control.\n\nSpecifications\n\n\nSensor – DS18B20 digital temperature sensor\n\nInput Voltage – 3.0–5.5V\n\nTemperature Range – -55°C to +125°C\n\nAccuracy – ±0.5°C (-10°C to +85°C)\n\nResolution – Programmable 9 to 12 bits\n\nInterface – 1-Wire\n\nProbe Diameter – 7 mm\n\nProbe Length – ~26 mm\n\nOverall Length (with wire) – 6 ft (~1.8 m)\n\nWaterproof – Sealed stainless steel probe\n\n\nWiring\n\nRed – Vcc\nBlack – GND\nWhite – Signal (Data)\n\n\nIdeal For\n\nLiquid temperature monitoring (aquariums, brewing, hydroponics)\nHVAC and environmental controls\nMulti-point temperature sensing on a single bus\n\n\nPackage Contents\n\n1× Waterproof DS18B20 Temperature Probe\n\n\nResources\n\nDatasheet (PDF)\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3129,"title":"Default Title","sku":"SF-SEN-18367","price":24.87,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":144,"option1":"Default Title"}]}
