Infrared Sensors
Infrared sensors are electronic devices that detect and measure infrared radiation (heat) emitted by objects in their field of view. They operate by converting infrared energy into electrical signals, enabling applications like temperature measurement, motion detection, and object recognition without physical contact. These sensors are widely used in consumer electronics, industrial automation, security systems, and environmental monitoring.
Developers should learn about infrared sensors when building IoT devices, smart home systems, or robotics that require non-contact sensing, such as for presence detection, thermal imaging, or gesture control. They are essential for projects involving automation, energy efficiency, or safety monitoring, where detecting heat or motion without direct interaction is critical.
