This Waterproof Temperature Sensor is great for measuring temperature where it's wet. As opposed to our regular Temperature Sensor TS-195 this temperature sensor has a 3 foot long wire and is encased in PVC to make it waterproof with a 3 cm metal probe at the end. Please note, this is a digital sensor which uses the 1-wire interface, meaning you only have to connect a single digital wire to get the signal. However, the 1-wire interface is a bit advanced as it requires code to parse out the data via the protocol. For beginners, we strongly recommend our regular analog TS-195 Temperature sensor mentioned above.

Specifications:

  • Operating Temperature: -55 °C to +125 °C
  • Low Voltage Operation (+3.0 V to +5.5 V)
  • 1-Wire Interface requires only 1 digital pin for communication
  • ±0.5°C Accuracy Over Temperature (from -10°C to 125°C)
  • User Selectable 9 to 12 bit Resolution
  • User Definable Temperature Limit Alarm Available
  • Each has a unique 64-bit serial code, allowing multiple temperature sensors to function on the same wire
  • Max Reading Delay: 750ms
  • Wiring:
    • Black/Green: Ground
    • Red: 3 - 5V
    • Yellow: Data
