1.3 Transducer Details
1.3.1 Temperature/Humidity Transducer
The Breeze/Breeze-V/Vivid+ includes a combination temperature/humidity transducer from
Sensirion (SHTC3). It is a small footprint, very low power device. It features operation over I

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
1
Baseline use case assumes room temperature, LoRa Tx power of 15 dBm, LoRa SF 10, and LoRa BW of 125 kHz.
Optimal battery settings use the default report settings and with dynamic reporting mode enabled. PIR motion
detection is assumed to be very frequent during active hours and very infrequent during inactive hours.

The sensor provides light intensity measurements, but they are not calibrated in lux. See the Technical Reference
Manual for more details [3].
