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