This 2m long One Wire Temperature Sensor has a waterproof probe and long wire shape, suitable for immersive temperature detection. The chip inside this sensor is DS18B20 which is widely adopted.

The original one includes three wires inside. You need to add an extra resistance to get it working. So for this sensor, we adjusted it into a Grove port and had a resistance pre-assembled inside so that you can use it as a regular Grove sensor. This makes it an easy connected one wire temperature senor for Seeeduino,which is derived from Arduino and compatible with all Arduino platforms.

For convenience, we have listed some resources at the bottom of this page. You can also find tons of resources from Google or other OSHW communities.


The cable part cannot be put under temperature higher than 70°C for a long time.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
