3.4.4.1
Temperature/RH/MCU Temperature Transducer Sample Period: Idle
The idle sample period determines how often the transducer is checked when the reported
value is within the threshold window.
Note:
When first enabled, the transducer starts in the Idle state.
3.4.4.2
Temperature/RH/MCU Temperature Transducer Sample Period: Active
The active sample period determines how often the transducer is checked when the reported
value is outside the threshold window.
3.4.4.3
Temperature/MCU Temperature Threshold
Temperature thresholds are stored in a single 2-byte register, with the upper byte storing the
‘high’ temperature threshold, and the lower byte storing the ‘low’ temperature threshold with
a 1°C per bit precision. Each temperature threshold is stored/transmitted as a 1-byte 2-s
complement number.
The ‘high’
temperature
threshold must be greater than the ‘low’
temperature threshold.
3.4.4.4
RH Threshold
The RH threshold is stored in a single 2-
byte register, with the upper byte storing the ‘high’
RH
threshold, and the lower byte storing the ‘low’
RH threshold with a 1% per bit precision. Each
RH threshold is stored/transmitted as a 1-byte unsigned number. The
“
high
”
RH threshold must
be greater than the
“
low
”
RH threshold.
3.4.4.5
Temperature/RH/MCU Temperature Transducer Threshold Enabled
The <transducer> Thresholds Enabled register enables and disables the threshold reporting on
the specified transducer. Thresholds and Sample Period values can be configured but are not
activated unless the Thresholds Enabled bit is set.
