Waterproof 1-Wire DS18B20 Digital temperature sensor
Product ID: 381This is a pre-wired and waterproofed (with heat shrink) version of a 1 Wire DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances!...$9.95In stock -
High Temp Waterproof DS18B20 Digital temperature sensor + extras
Product ID: 642This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C - the limit of the sensor itself. That said, it's...$14.95In stock -
DS18B20 Digital temperature sensor + extras
Product ID: 374These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analog converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the...$3.95In stock -
Adafruit Chainable DS18B20 Extender Breakout - STEMMA JST PH 2mm
Product ID: 5971One of the perks of working at adafruit is you get to request hardware - and you'll probably get fast turnaround! One of our adafruit.io developers requested "an easy way to chain DS18B20 sensors for testing with adafruit.io's wippersnapper service" at 11:54am one Monday morning, and after a few back-and-forth's we came up with the Adafruit Chainable DS18B20 Extender...$4.5095 in stock -
Adafruit DS2482S-800 8 Channel I2C to 1-Wire Bus Adapter - STEMMA QT / Qwiic
Product ID: 6027This is a DS2482S-800 Stemma QT board that uses a I2C-to-1W controller chip, with 8 selectable channels, built-in parasitic-power-pullups, adjustable I2C address and a wide operating voltage range! You can easily connect it to an existing I2C bus and then use the breakout pads to attach multiple DS18B20's, or pair it with our 1-Wire chaining breakouts for fancier...$19.955 in stock -
High Temp Waterproof DS18B20 Digital Temperature Sensor - 3m long
Product ID: 3846This is a pre-wired and waterproofed version of the DS18B20 sensor made with a PTFE wire cable. Handy for when you need to measure something far away, or in wet conditions. This sensor is a little more expensive than the other waterproof version we have with a PVC cable because this one can be used up to 125°C - the limit of the sensor itself. That said, it's...$19.95In stock -
Food-Grade Heat Shrink - 3/8" diameter 12" long
Product ID: 1020We decided to stock this food-safe heat shrink specifically for people who were building beer-brewing or sous-vide projects using our waterproof DS18B20+ digital temperature sensors. This heat shrink is FDA Compliant for contact with food. The end of the sensor is stainless steel, but the jacketing is PVC, not good for dunking into your food or drink! But this heat...$3.9551 in stock -
Adafruit DS2484 I2C to 1-Wire Bus Adapter Breakout - STEMMA QT / Qwiic JST SH 1mm
Product ID: 5976By customer request, this is a DS2484 Stemma QT board that uses a I2C-to-1W controller chip, with ESD protection and support for split supplies. You can easily connect it to an existing I2C bus and then use the screw terminals to attach multiple DS18B20's, or pair it with our 1-Wire chaining breakouts for fancier experimentation. You're probably familiar with the...$7.50Out of stock
