Digital 1-Wire water-resistant temperature sensor is based on the DS18B20 chip covered by a stainless steel cap. Each sensor features RJ45 plug and can be connected to any UniPi controller with 1-Wire bus. A single bus supports up to 15 sensors (the response time can be higher in such connections). Number of sensors connected to a single controller can be further increased by utilizing corresponding patchcords or the 8-port with an integrated DIN rail holder

Several hubs can be connected in cascade. More info about connecting 1-Wire sensors can be found on this link

Sensors are universal, their temperature range is -55/+85 °C (-67/+185 °F)

Sensor dimensions

Practical use examples

  • measuring indoor/outdoor temperature for the purpose of heating switching
  • measuring temperature of liquid stored in tanks (for more precise measurements it is possible to use more sensors located in several levels)
  • measuring liquid transport lines temperature
