Abstract: A method of and system for determination of measured parameter gradients for environmental system control is presented. A system includes a sensor assembly with a first face opposite to and spaced apart from a second face and first and second sensors. The first sensor is adjacent to the first face and senses a first value of an environmental variable nearby. The second sensor is adjacent to the second face and senses a second value of the environmental variable nearby. The system includes a processor and a memory with instructions that cause the processor to: receive the first and second values and estimate a third value of the environmental variable at a distance spaced apart from the second face based on the first and second values. The system includes a sensor communication system for transmitting information including at least one of the first, second, and third value of the environmental variable.

Abstract: A method of and system for automatically adjusting airflow is presented. A system includes a controlled supply register that has an airflow adjusting mechanism that controls an aperture through which air passes and a register sensor that senses a value of an environmental variable in system duct work. The register also includes a communication system and a processor system that controls the airflow adjusting mechanism. The system also includes a sensor platform that senses an environmental variable in a space and transmits and receives information. The system also includes a controller that receives information about the environmental variables and a desired set point for the environmental variable in the space. The controller determines a target airflow to achieve the desired set point and transmits information about the target airflow. The register receives information about the target airflow and controls the register adjusting mechanism to achieve the target airflow.
