Temperature Sensor Datasheet

Spring, 2016

OverviewAccessory Box - Outline.png

The temperature sensor is an accessory that allows up to 3 simultaneous temperature measurements with ± 0.4°C accuracy.   Temperature thresholds can be established on the device’s configuration that allows you to combine with other conditions for highly customized event reporting.

The temperature sensor is fully integrated with the Pegasus Gateway and its APIs.

FAQ

How long can I extend the 1-wire cable to install inside a cabin?

The 1-wire cable from the Syrus to the temperature sensor can be extended up to 20 meters.  Make sure you use the same cable gauge or a thicker gauge when extending this cable.  Consider using a twisted cable like UTP CAT5e.
