heat sensors
Infrared motion finders
Heat sensors are devices that detect temperature or thermal radiation, converting heat energy into electrical signals for measurement or triggering responses.
They appear in everything from home thermostats and smoke detectors to industrial equipment and wildlife cameras.
The security system uses heat sensors to detect intruders.
In nature, some animals like pit vipers have biological heat sensors that allow them to locate warm-blooded prey in complete darkness.
