# NWIN003 OWxValue & OWxHealth

The **OWxValue** fields are the latest temperature values read for each of the 3 digital temperature sensors that can be connected to the NWIN003 node. x is the sensor number ranging from 1 to 3.

The health status indicator of the sensor can be checked to determine if a reading is valid.

The **OWxHealth** fields are the health status indicators of the 3 external temperature sensors. Each time the node successfully reads the sensor it increments this health indicator until it reaches 3 and then it stops incrementing it. If the node fails to read the sensor it decrements this value until it reached 0 and then it stops decrementing it.

<table><thead><tr><th width="138">OWxHealth</th><th>Meaning</th></tr></thead><tbody><tr><td>3</td><td>The temperature value shown in OWxValue is valid</td></tr><tr><td>2</td><td>The value shown in OWxValue may be valid depending on the previous value (2 -> 1: not valid value, 1 -> 2: valid value)</td></tr><tr><td>1</td><td>The value shown in OWxValue may be valid depending on the previous value (2 -> 1: not valid value, 0 -> 1: valid value)</td></tr><tr><td>0</td><td>The value shown in OWxValue is invalid and is an old reading</td></tr></tbody></table>

&#x20;In normal operations the OWxHealth for a connected sensor should always be 3, but if a new sensor is connected a moment ago or a sensor is defective other values may be present.
