Webb14 maj 2024 · Most smart motion sensors work by using passive infrared (PIR) technology. PIR sensors detect infrared energy, which humans and other animals give off as body heat. So, when a sudden increase in temperature occurs, your device will notice the change and proceed to alert your system’s control panel. Webb30 juni 2024 · PIR sensors can be more sensitive in colder temperatures, as the difference between ambient and body temperature is bigger. On a hot day, they can be less sensitive. However, normally, this isn’t an issue since they’re usually designed for lights that only need to switch on at night when it’s cooler. Let’s explore this a little more by looking at:
