Waterproof DS18B20 probe at Adafruit

As luck would have it, about a week or two after building the DS18B20 temperature probe from scratch since I didn’t want to wait for it to ship from China, Adafruit has added a similar probe to their product lineup. The Adafruit probe looks very similar to the Arduino-Direct one, but Adafruit is US based so shipping would be much faster and as always they provide great documentation on how to use it.

From their documentation it looks like if you wanted to use it with my Easy Arduino 1-Wire Sensor Network you would connect it as follows:

  • Red -> Vdd
  • Black -> GND
  • White -> DQ

You can order the sensor from Adafruit at http://www.adafruit.com/products/381.
