Temperature/RH Threshold Configuration 

In all Home Sensor modules 

before Rev D

, Temperature and RH are only compatible with the 

Base and External Connector models. 

The Home Sensor supports threshold transmission on three different transducer outputs: 

•

 

Temperature:  Located in the Temp/RH transducer 

•

 

RH:  Located in the Temp/RH transducer 

•

 

MCU Temperature:  Located inside the MCU (with lower accuracy compared to 
Temperature and RH) 

When a threshold is enabled, the Home Sensor reports the transducer value when it leaves the 
configured threshold window, and once again when the transducer value re-enters the 
threshold window. The Threshold mode is compatible with periodic reporting. Table 3-10 shows 
a list of configuration registers for the Temperature/RH Threshold setting.
