A pest detection device including a capacitive sensor having a plurality of traces that can be capacitively sensed using self-capacitance or mutual capacitance measurements. The sensor including conductive shield traces to facilitate a number of sensing applications. The sensor including a coated portion to facilitate crawling of pests over the sensing area of the circuit board.

Pest detection using sensor with textured surface

A system for detection of equipment connections to a thermostat. The thermostat has one or more terminals with a one-to-one connection to one or more loads respectively of heating, ventilation and/or air conditioning equipment, and one or more terminals with a one-to-one connection to electrical power. One or more detectors are connected one-to-one to each of the one or more terminals, respectively, for connection to the one or more loads, and the one or more connections to the electrical power. Each detector is connected to a processor. Each detector is configured to provide a signal to the processor relative to a corresponding terminal indicating a status of a connection of the terminal to a load or to the electrical power.

Detection of HVAC equipment wired to a thermostat

A device for detecting a wire configuration connecting a thermostat and HVAC equipment includes fan controller circuitry, AC controller circuitry, switching circuitry, and processing circuitry. The fan controller circuitry is configured to operate a fan unit of the HVAC equipment using a G pin in a first wire configuration and using a K pin in a second wire configuration. The AC controller circuitry is configured to operate an AC unit of the HVAC equipment using a Y pin in the first wire configuration and the K pin in the second wire configuration. The switching circuitry is configured to refrain from electrically coupling the Y pin and the K pin in response to a deactivation signal. The processing circuitry is configured to determine the HVAC equipment is in the first wire configuration in response to determining the AC controller circuitry receives power while outputting the deactivation signal to the switching circuitry.

A retrofit damper system is configured for installation in existing ductwork including a duct supplying conditioned air through a register boot to a register vent. The retrofit damper system includes a damper assembly including a damper blade and a damper motor configured to drive the damper blade between a closed end position and an open end position. A control module includes a control module housing and a controller within the control module housing that is configured to regulate operation of the damper motor. The controller outputs a drive signal that causes the electric damper motor to drive the damper blade to the desired position and creates a plurality of interruptions in the drive signal while driving the damper blade. A sense circuit senses back EMF signal, and the controller estimates a blade position based at least in part on the back EMF signals.

A wireless occupancy sensor that is configured to be deployed within a building space includes a sensor body, an occupancy sensor that is housed by the sensor body, a light emitting diode (LED) that is housed by the sensor body, a wireless transceiver that is housed by the sensor body and is configured to be in wireless communication with a remote device. A controller is housed by the sensor body and is operably coupled to the occupancy sensor, the LED and the wireless transceiver and is configured to receive via the wireless transceiver a request to illuminate the LED from the remote device and in response to receiving the request, illuminate the LED in order to help visually identify the wireless occupancy sensor in the building space.
