Abstract:
Various embodiments of wireless ambient sensor unit are presented. The sensor unit may include a wireless transceiver configured to transmit sensor data and to receive instructions. The sensor unit may include a sensor configured to measure an ambient condition. The sensor unit may include a controller in communication with the wireless transceiver and the sensor. The controller may be configured to compare data measured about the ambient condition to a stored threshold while the wireless ambient sensor unit is functioning in a low-power mode. The controller may be configured to exit the low-power mode in response to the comparison of the data with the stored threshold. The controller may be configured to cause the data measured about the ambient condition to be transmitted by the wireless transceiver as one or more messages in response to the comparison to the stored threshold.
Abstract:
An Electronically-Controlled Register vent (ECRV) that can be easily installed by a homeowner or general handyman is disclosed. The ECRV can be used to convert a non-zoned HVAC system into a zoned system. The ECRV can also be used in connection with a conventional zoned HVAC system to provide additional control and additional zones not provided by the conventional zoned HVAC system. In one embodiment, the ECRV is configured have a size and form-factor that conforms to a standard manually-controlled register vent. In one embodiment, a zone thermostat is configured to provide thermostat information to the ECRV. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones.
Abstract:
A low cost, robust, wireless sensor that provides an extended period of operability without maintenance is described. The wireless sensors are configured to communicate with a base unit or repeater. When the sensor unit detects an anomalous ambient condition (e.g., smoke, fire, water, etc.) the sensor communicates with the base unit and provides data regarding the anomalous condition. The sensor unit receives instructions to change operating parameters and/or control external devices.

Abstract:
Various devices, systems, and methods may be presented. A wireless device may include a smoke sensor configured to obtain measurement data regarding a level of smoke. The wireless device may operate in a sleep mode while the smoke sensor obtains the measurement data. The wireless device may determine, from the measurement data, whether the level of smoke has exceeded a warning threshold. In response to determining that the level of smoke has exceeded the warning threshold, the wireless device may communicate a warning indication. The wireless device may determine, from the measurement data, whether the level of smoke has exceeded an alarm threshold. In response to determining that the level of smoke has exceeded the alarm threshold, the wireless device may communicate an alarm indication, the alarm indication indicating that the alarm threshold has been exceeded.
Abstract:
Various devices, systems, and methods may be presented. A sensor unit may be presented that includes a housing and a chamber arranged within the housing. The sensor unit may include a controller arranged within the housing. The controller may receive information from an HVAC (heating ventilation and air conditioning) system, wherein the information is indicative of operation of the HVAC system. The controller may determine an effect of the HVAC system on measurements made by the sensor using the information from the HVAC system.
Abstract:
An arrangement for measuring environmental conditions in a wireless sensor system. A threshold value may be determined. An environmental condition sensor unit may measure, over a defined period of time, an environmental condition level. The measured environmental condition level may be compared to the determined threshold value. It may be determined whether the measured environmental condition level exceeds the defined threshold value for the defined period of time. At least in part based on the determination of whether the measured environmental condition level exceeds the defined threshold value over the defined period of time, information indicative of the measured environmental condition level may be transmitted.
