For simple and easy temperature measurement using the 1-wire protocol with a prepared DS18B20 sensor.
The DS18B20 is a well-adopted temperature sensor that features the 1-wire protocol. SeeedStudios has prepared the sensor into a tidy probe with a 2M (6.6') long waterproof cable.
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.
NOTE: The cable portion cannot be put under temperature higher than 70°C for a long time.
