摘要:
An environmental control system for a space including at least one window adapted for admitting light into the space. The system comprises an environmental controller (such as a fan, a light, an HVAC system, a window, a window covering, or any combination of the foregoing) for regulating an environmental condition, and at least one first sensor, such as a radiant heat flux sensor, for sensing an amount of radiant energy associated with the space and generating an output. A controller is provided for controlling the operation of the environmental controller based on the sensor output. Related methods are also disclosed.

An apparatus is provided for controlling environmental conditions using a fan and a light in connection with a building having a space including a partition, such as a wall. The apparatus may include a control adapted for being mounted to the partition and for coordinating the control of the fan and the light based on a sensed condition, such as temperature or occupancy. Groups of like devices for controlling environmental conditions may be similarly controlled, such as using control. Control may also provide an indication of an operational state of the device(s) controlled by it, or provide for control based on a preference of one or more people upon detecting their presence. Related methods are also described.

An environmental monitor device with a database comprises a data bus, a multitude of sensors, at least one processing unit, input/output device(s); communications interface(s), and memory. Communications interface(s) communicate with at least one environmental sensor device comprising with a multitude of sensors. The multitude of sensors may include particle counter(s), pressure sensor(s) and/or the like. The memory is configured to hold data and machine executable instructions. The machine executable instructions are configured to cause at least one processing unit to: collect sensor data from at least one environmental sensor device; store at least some of the sensor data in at least one database; and generate a report of sensor data that exceeds at least one threshold.

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.

The thermostat has a power switch to select one of Heater and Cooler for the HVAC system, a light sensor (200) to sense ambient lighting, a temperature sensor (210) to sense ambient temperature, a manual temperature switch (260) to set a desired temperature for the room, a control circuit (220) to select a preferred temperature based on selection of the power switch, an illuminating outer cover (110), which at least partially covers the outside of the thermostat, which displays one of Blue and Red colors according to selection of the power switch and the ambient lighting, and a plurality of LED displays (140) arranged on a display face of the thermostat, to display one arrangement of the LEDs based on a difference between the preferred temperature and the ambient lighting.
摘要:
Filters are monitored. Color data is determined for a filter. A filter status for the filter is derived from the color data. An action is taken based on the filter status. The filter status may include a dirty status or an empty status for the filter. The action may include alerting a user based on the filter status. The filter may be illuminated prior to the determining of the color data for the filter.

Controlled appliance and method for controlling interactions between the controlled appliance and a remote control device. The controlled appliance comprises a BLE interface and an actuation module. The controlled appliance sets the BLE interface in a scanning mode where the BLE interface is capable of receiving BLE signals from other devices. The controlled appliance receives, via the BLE interface, a BLE advertising signal from the remote control device. The controlled appliance establishes a connection between the controlled appliance and the remote control device through the BLE interface. The controlled appliance exchanges data with the remote control device via the BLE interface. Upon reception from the remote control device via the BLE interface of a command for controlling operations of the actuation module, the controlled appliance applies the command to the actuation module.
