An IR sensor uses infrared radiation to detect the presence of an object or obstacle by measuring the heat emitted or reflected by the object.
An IR sensor detects infrared radiation from objects or measures reflected infrared signals. Changes in infrared energy are converted into electrical signals, allowing the sensor to identify motion, proximity, or temperature differences in applications like alarms, appliances, and control systems.
An IR sensor functions by emitting infrared light and monitoring the changes when it reflects off surfaces. Variations in intensity help determine distance, motion, or presence, making these sensors valuable in automation, robotics, security, and electronic devices.
