Light intensity alarm function:
HI_LUX_TRESHOLD
LO_LUX_TRESHOLD
ALARM
The sensor compares the temperature, humidity and light intensity measured
against the parameters that defi ne the alarm limits.
There are no delays in activating the alarm signal; as soon as the acquired
value is higher than the maximum limit or lower than the minimum limit the
corresponding fl ag is activated.
If Temperature > High temperature limit --> high temp. alarm =1
If Temperature ≤ High temperature limit --> high temp. alarm =0
If Temperature < Low temperature limit --> low temp. alarm =1
If Temperature ≥ Low temperature limit --> low temp. alarm =0
If Humidity > Maximum humidity limit --> maximum humidity alarm =1
If Humidity ≤ Maximum humidity limit --> maximum humidity alarm =0
If Humidity < Minimum humidity limit --> minimum humidity alarm =1
If Humidity ≥ Minimum humidity limit --> minimum humidity alarm =0
If Light > Maximum light limit --> maximum light alarm =1
If Light ≤ Maximum light limit --> maximum light alarm =0
If Light < Minimum light limit --> minimum light alarm =1
If Light ≥ Minimum light limit --> minimum light alarm =0
