There is really no such thing as a purely digital temperature sensor. There are however integrated sensors that provide a digital output. These sensors can be calibrated at the factory and since the output is digital there is no error or loss in the signal.
The ezeio works with a type of digital temperature sensor from Dallas Semiconductor. These sensors are programmed with a unique serial number which allows our system to detect the type of sensor and automatically set up suitable configurations.
These sensors are suitable for measuring from -55°C to +125°C and are available in a rugged waterproof steel casing
