If smart lights, thermostats and security cameras are the staples of the smart home, think of smart sensors as the invisible network meshing everything together. Or, if you prefer, the eyes of the smart home.
Look around you at all the gadgets and appliances labeled as “smart” and you’ll find impressive integrated microcontrollers, SoCs and wireless connectivity inside. In an Internet of Things (IoT) age, consumers expect their home appliances to do more—and they indeed do.
But the brains of today’s smart home appliance—MCUs and SoCs—are surrounded with basic yet hugely important peripheral devices. These peripheral sensors, timers, controllers and crystal oscillators are the sight, touch and sound “senses” that feed the home appliance’s smart brain.
Everything from toasters and window air conditioners, to coffee pots, thermostats and even smartphones rely on these elegant peripherals to help save energy, seamlessly interact with the consumer, or provide an enhanced user experience.
The best part about using sensors is that they’re (mostly) super easy to install, often with no wiring required.Many of the sensors you pick up today are wireless and battery-powered, allowing you to place them wherever you like.
Sensors can also be used to transmit data to your different smart home devices. If you have a hub-based smart home, using SmartThings, HomeKit, Google Assistant or Alexa to tie everything together, sensors are another form of control, triggering routines and automations just by "sensing" your presence.
Some smart home appliances also double as sensors of sorts. Smart doorbells have motion sensors in them and send you an alert when they see motion, and smart thermostats have temperature sensors in.
