# [TEMPERATURE ALARM LIMITS](#TEMPERATURE_ALARM_LIMITS)

When the device exceeds either *temphigh* or *templow* temperature threshold the device is in the alarm state, and will appear in the alarm directory. This provides an easy way to poll for temperatures that are unsafe, especially if *simultaneous* temperature conversion is done.

Units for the temperature alarms are in the same *temperature scale* that was set for *temperature* measurements.

Temperature thresholds are stored in non-volatile memory and persist until changed, even if power is lost.

## [temphigh](#temphigh)

*read-write, integer*  
Shows or sets the lower limit for the high temperature alarm state.

## [templow](#templow)

*read-write, integer*  
Shows or sets the upper limit for the low temperature alarm state.
