on Google Store Designed to replace not just an ordinary smoke detector, this home safety device can also be used for general home security. In addition to detecting the presence of smoke with its photo-electric sensor, the Owl Wired can also sniff out carbon monoxide using an electromechanical sensor, track temperature and humidity levels in your home, detect motion with a microwave radar sensor, and it has an onboard microphone that can analyze noise levels. The motion detector can send you an alert if motion is detected when you think your everyone in your home should be at rest, and you can program its microphone to send you an alert when noises exceed a defined threshold.
