Abstract: A heating, ventilation, or air conditioning (HVAC) system with automated flow direction detection is provided. The HVAC system includes one or more hoses configured to provide airflow from HVAC equipment, a bidirectional pressure sensor coupled to the hoses, and a controller coupled to the bidirectional pressure sensor. The controller is configured to receive a signal from the bidirectional pressure sensor, determine a direction of the airflow relative to the bidirectional pressure sensor based on the signal, correct the signal for a reversed hose polarity relative to the bidirectional sensor based on the direction of the airflow, and perform a control activity using the corrected signal.

Abstract: An illustrative embodiment disclosed herein is a circuit for sensing heating, ventilation, air conditioning, and refrigeration (HVACR) equipment. The circuit includes an input port that has an input voltage signal. The circuit includes an analog-to-digital converter (ADC) generating a first digital signal based on receiving a representation of a supply voltage, generating a second digital signal based on receiving the divided input voltage signal, and outputting the first digital signal, the second digital signal, and an output voltage reference. The circuit includes an amplifier coupled to the ADC and amplifying the output voltage reference to generate a supply voltage. The circuit includes a microprocessor coupled to the ADC and configured to calculate a first ratio of the first digital signal and the supply voltage. The microprocessor is configured to determine the input voltage signal by calculating a second ratio of the second digital signal and the first ratio.

Abstract: Implementations herein relate to visualization of interaction with a building management system (BMS). Such interaction may be facilitated with a smart headset that displays a three-dimensional model of an image with real-time data from the BMS to enable monitoring and control of the BMS. In one implementation, a system for locating a target in a building includes a server, a first wireless emitter, and an application on a mobile device. The first wireless emitter is associated with the target and configured to emit a first emitter identifier within a first range. The application is configured to detect the first emitter identifier when the mobile device is within the first range. The application is also configured to transmit the first emitter identifier to the server in response to detecting the first emitter identifier. The application is also configured to receive a first content from the server.
