Smart sensors are environmental sensors (temperature, humidity, air quality), smart utility meters (electricity, water, gas), smart waste bins. Often low-power, long-range wireless communication.
Detailed Explanation
Smart sensors are specialized devices designed to monitor and measure environmental parameters such as temperature, humidity, and air quality. They can also serve various functions, like tracking energy usage through smart utility meters for electricity, water, and gas. One key characteristic of smart sensors is their ability to communicate wirelessly over long distances while consuming minimal power, making them ideal for deployment in remote or hard-to-reach locations.
Examples & Analogies
Imagine a smart thermostat in your home that can detect the temperature and humidity levels. It has the capability to communicate with your smartphone, allowing you to check or adjust the temperature from anywhere. Similarly, think of a smart waste bin that signals when it is full, so the collection service knows exactly when to empty it, thereby optimizing waste management.
