The sensor you select will depend on your family’s needs – do you live in a flood-prone climate, for example, and therefore require a sensor that will predict weather patterns and adjust for humidity? If, on the other hand, you live in the high desert, you may wish for a sensor which adjusts to temperature. City dwellers may need a motion security sensor only.
That being said, here are a few places to start: the Ecolink Z-Wave PIR Motion Detector with Pet Immunity means that your alarm won’t go off every time your pet crosses the room. Priced affordable, the Ecolink Z-Wave PIR is a popular choice for consumers across the nation. Aeon Labs also makes a variety of easy-to-use, multi-use sensors which range in price and ability. The Aeotec Multisensor 6, for example, is “packed with intelligence,” detecting not only motion but also monitoring temperature, light, humidity, and even vibration – which comes in handy if an intruder is tampering with the device. Of course, vibration detectors identify and record seismic activity as well.
If it’s a garage door sensor you’re after, you might invest in the Telguard GDC1 Universal Z-Wave Garage Door Control Switch, which ensures that your garage door opens and shuts when you want it to – even if you aren’t home to monitor it.
