One Wire Temperature Sensor DS18B20 by Seeedstudio

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 the widely adopted DS18B20. For convenience, we suggested some resources at the bottom. But you can still find tons of resources with a quick Google search or over other OSHW communities.

The original one includes three wires inside. You need to add an extra resistance to get it working. 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.

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