Digital Temperature Sensor with 1-Wire Interface measures temperatures between -55 and +125 degrees Celsius.
Libraries for this sensor type and different programming environments, for example for Arduino or Raspberry, are available and easy to find.
A temperature alarm condition can be programmed right in the sensor (nonvolatile).
Every sensor element comes with a unique, digital serial number. Therefore, multiple sensors can be connected to the same 1-Wire interface.
– voltage supply 3.0 to 5.5V DC
– operating current ca. 1.5mA
– standby current ca. 3uA
– transmission current 1mA/4mA (logic 1/0)
