Digital Temperature Sensor DS18B20 – Watertight – 1 Wire Interface – 3 Meter Wire
FREE Canada & USA shipping available (see details)
This Digital Temperature Sensor with the simple 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.
The sensor element is not considered to be watertight, use it under wet conditions at your own risk.
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.
– overall length is 300cm
– probe size is about 50 x 6mm
– voltage supply 3.0 to 5.5V DC
– operating current ca. 1.5mA
– standby current ca. 3uA
– transmission current 1mA/4mA (logic 1/0)
