1. A mean radiant temperature sensor device system, comprising:
a two or more degree-of-freedom motion system comprising a first motor or servo configured to rotate a first component around a first axis and a second motor or servo configured to rotate a second component around a second axis orthogonal to the first axis;
a non-contacting temperature sensor operably connected to the two or more degree-of-freedom motion system;
data storage; and
a processor configured to control the two degree-of-freedom motion system and receive data from the sensor,
wherein the data storage contains instructions that, when executed by the processor, allows the mean radiant temperature sensor device system to calculate mean radiant temperature (MRT), and perform at least one function selected from the group consisting of:
occupancy detection, counting objects or individuals, locating objects or individuals in a volume of space, tracking an object or individual over time and space, detection of unsafe environmental conditions, characterization of unsafe environmental conditions, tracking of unsafe environmental conditions, detection of gases, detection of liquids, characterization of gases, characterization of liquids, tracking of gases, tracking of liquids, analysis of buildings, determination of control metrics for a building or volume of space, generation of 3D and 2D models or representations of spaces and buildings using data from the sensor, generating 2D images of surfaces, generating 2D images of scenes, generating 2D images of environments, generating 3D point clouds of surfaces, generating 3D point clouds of scenes, generating 3D point clouds of environments, controlling actuators, controlling HVAC systems with data other than mean radiant temperature (MRT), informing HVAC systems with data other than MRT, controlling building systems other than HVAC, estimating a metabolic rate using surface temperature information from the sensor, estimating the thermal capacitance of living organisms, receiving input from occupants, requesting input from occupants based on data from the sensor, controlling the environmental conditions based on a combination of input from occupants and data from the sensor, calibrating energy models for heat loss and insulation levels in building simulation and analysis, commissioning building systems to ensure appropriate comfort via measurement of MRT, and quantifying and confirming energy savings and operational performance of buildings.
