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. Features Requires only one wire for data interface Waterproof Grove compatible Accepts 3.0V to 5.5V power supply Wide temperature range: -55°C to +125°C High accuracy: ±0.5°C( -10°C to +85°C) Resources DS18B20 datasheet Arduino libraries mbed cookbook Caution: The cable part cannot be put under temperature higher than 70°C for a long time.
