1.2.1 Transducer Details
1.2.2 Temperature/Humidity Sensor
The Room Sensor includes a combination temperature/humidity transducer from Sensirion
(SHTC3). It is a small footprint, very low power device. It features operation over I

C protocol
and operates from 0% to 100% RH and -40°C to 125°C with a typical accuracy of ±2% RH and
±0.2°C. The typical and maximum accuracies specified across the operating relative humidity
and temperature range of the sensor are shown in Figure 1-2 and Figure 1-3, respectively.
