A building system can connect to temporary air quality sensors installed throughout spaces of the building for a period of time. The building system can receive air quality measurements of the temporary air quality sensors over the period of time and disconnect from the temporary air quality sensors at an end of the period of time, wherein the temporary air quality sensors are uninstalled at the end of the period of time. The building system can generate a control strategy based on the air quality measurements, the control strategy for controlling equipment of the building to improve air quality of the building and cause a building management system to implement the control strategy to control the equipment of the building to improve the air quality of the building.

An autonomous device for measuring at least one characteristic of a fluid circulating in a conduit in a flow direction comprises a permanent magnetic field source, a magneto-electric converter and a processing circuit capable of using the electric charges supplied by the converter to supply a measurement of a characteristic of its environment. The source and the converter are placed in a stator and a rotor forming the device. The autonomous device further comprises attachment means allowing the stator to be fixedly placed in the conduit or at one end of the conduit, in a configuration in which the axis of rotation of the rotor is parallel to the flow direction. A control system may employ at least one such autonomous device.

An air quality system handled by artificial intelligence internet of things is provided and includes a gas detection device, an artificial intelligent internet of things handling device, and a user demand platform. In the system, the user demand platform transmits an instruction to the artificial intelligent internet of things handling device. By using self deep-learning analysis of data computing and algorithms of the AI device, second digital data is generated. The second digital data is fed back to the gas detection device through the network. Accordingly, the actuating actions of the micro pumps and the detecting actions of the sensors can be generated. Hence, the actuation and the detection of air quality can be achieved more effectively.

A software implementation and method for garage ventilation control logic to intelligently modulate the rate of speed of a plurality of garage fan motors in an enclosed commercial parking garage structure. The savings are primarily driven by the known cubic relationship between fan power draw and fan speed, whereby fans operating at lower speeds will draw much less power than operating at higher speeds, taking advantage of the highly non-linear relationship between the two.

The present invention relates to an air quality monitoring and controlling system and method for enclosed spaces, which provides an innovative closed loop (i.e., inline real time feedback) air management process, utilizing learning and prediction capabilities to provide with effective air purification and reliable alerting when required.

A central controller for an intelligent environmental air management system includes at least one processor and memory storing instructions executable by the at least one processor. The instructions, when executed, cause the central controller to detect and communicate with an air hazard sensor, an environmental condition monitor, and an air hazard mitigation device of the intelligent environmental air management system.

A ventilation fan includes a body unit, which has a fan disposed in a body case and a fan controller operable to control an air volume of the fan. The ventilation fan also includes a sensor module having an indoor environment detecting sensor and a module controller operable to control a detecting operation of the indoor environment detecting sensor. The body unit has a module mount on which the sensor module is mounted and another sensor module can be mounted in place of the sensor module. The module mount is connected to the fan controller. The module controller outputs detection information obtained based on a detection result of the indoor environment detecting sensor to the fan controller, which in turn controls the air volume of the fan based on the detection information inputted thereto.

A building system operates to receive air quality measurements of a plurality of spaces of the building from a mobile air quality sensor, the mobile air quality sensor configured to collect the air quality measurements of the plurality of spaces while the mobile air quality sensor moves throughout the plurality of spaces of the building and provide the collected air quality measurements to the one or more processors. The air quality measurements include data identifying locations and times at which the air quality measurements were collected The building system operates to cause the one or more processors to store information, or a link to the information, in a database based on the collected air quality measurements, the database including a contextual representation of the plurality of spaces of the building and perform at least one operation using the information based on the air quality measurements.
