Abstract: HVAC components having improved efficiency are described. In one embodiment, excessive sleep current draw in a battery-powered device having a microcontroller is detected by measuring a voltage drop across a MOSFET device coupled in a forward-conducting orientation in series between the battery and the microcontroller, causing a transistor to conduct when the voltage drop exceeds a predetermined threshold to generate a first trigger signal, integrating the first trigger signal to generate a second trigger signal, and generating an interrupt to the microcontroller. In another embodiment, a battery-saving method of operating an HVAC component includes maintaining the HVAC device in the sleep mode, receiving a user input to wake the device, transmitting a data request and returning the HVAC component to the sleep mode, waking up the HVAC device to poll an adjacent network node storing a cached response, displaying the response, and returning the HVAC device to sleep.

Abstract: A method extends battery life of a battery powered indoor air quality (IAQ) sensor that includes a IAQ detector, a radio, the battery, and a microcontroller with a memory and a processor. The method includes detecting IAQ at predetermined intervals to provide IAQ levels, and storing the IAQ levels and corresponding timing data in the memory. The method further includes determining an occupancy schedule based on IAQ level patterns and subdividing the occupancy schedule into a plurality of periods. The method further includes determining an occupancy status of each of the periods based on the IAQ levels. The method further includes operating the IAQ detector to sample at an active interval when the occupancy status is the occupied and at an inactive interval when the occupancy status is the unoccupied. The inactive interval is longer than the active interval. The IAQ detector can be, for example, a CO2 detector or a VOC detector.
