Description
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. 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.
What is DS18B20?
The DS18B20 Digital Thermometer provides 9 to 12-bit (configurable) temperature readings which indicate the temperature of the device.
Information is sent to/from the DS18B20 over a 1-Wire interface, so that only one wire (and ground) needs to be connected from a central microprocessor to a DS18B20. Power for reading, writing, and performing temperature conversions can be derived from the data line itself with no need for an external power source.
Attention
The cable part cannot be put under temperature higher than 70°C for a long time
