Abstract
Various methods, systems, and devices for identifying a low battery charge of a smoke detector are presented. For example, a device may include a smoke detection sensor that detect smokes and, in response to detecting smoke, generate a smoke detection signal. The device may include battery test circuitry that tests a charge level of a battery installed in the smoke detector device. The device may include an audio output device that outputs a low battery chirp in response to the battery test circuitry determining the charge level of the battery installed in the smoke detector device is low. Also, the device may include a proximity detector that monitors for a wave movement of an object within a distance of the smoke detector device and generates a proximity detection signal when the proximity detector detects the wave movement performed by an object within the distance of the smoke detector device.
