Building Robotics Call for Innovation

SMART Sensor

The Spherical Motion Average Radiant Temperature (SMART) Sensor uses a low-cost LIDAR sensor and directional IR Thermopile on a two-axis scanning system to combine geometry-finding and surface temperature measurement for a complete characterization of a room's mean radiant temperature (MRT) - not just for a singular point, but for any given position within the room. The SMART Sensor can also detect human occupancy and position and thus calculate MRT specific to particular occupants, as well as supply a BMS with occupancy data. In full-scale building deployment, scanned room geometries can be stored in the BMS along with a Deployable SMART Sensor, allowing a smaller SMART Sensor to operate successfully without LIDAR.


Working prototypes have been constructed and geometric algorithms with graphical outputs have been developed for Diagnostic (with LIDAR) and Deployable (without LIDAR) units. Our sensors have been tested in existing building spaces and successfully diagnosed localized MRT problems in spaces with radiant cooling. The SMART Sensor optimizes high performance radiant heating and cooling systems and brings us closer to controlling thermal comfort of occupants rather than spaces.
