About the Sensor
The Bev/Art temperature and humidity sensor is among the smallest one commercially available, about the size of a LEGO® brick, and small enough to stay out of sight without compromising performance.
The sensor is built to keep working with little upkeep. On-device storage holds 30 days of data, so the record stays continuous through power and network outages. Battery life runs past 10 years, and setup is simple: place the sensors, plug in the gateway, and data starts streaming.
