Working Principle:
- IR sensors work based on the principle of detecting infrared radiation, which is not visible to the human eye but is emitted by objects as a form of heat.
- They typically consist of an IR transmitter (emitter) and an IR receiver (detector).
- The emitter emits infrared light, and the receiver detects the reflected or emitted infrared light from objects in its field of view.
- The presence or absence of an object, its distance, or its temperature can be determined based on the amount of IR radiation detected.
Components:
- IR sensors typically include an IR LED as the emitter and an IR photodiode or phototransistor as the receiver.
- Some sensors come as integrated modules, making them easier to use in projects.
Applications:
- IR sensors are widely used in remote controls for televisions, air conditioners, and other electronic devices.
- They are used in burglar alarms for motion detection.
- In robotics, IR sensors can be used for line following and obstacle avoidance.
- In industrial settings, they are used for non-contact temperature measurements.
- In automation, they are used for object detection and counting.
- IR sensors are also used in proximity sensing applications, such as automatic hand dryers and soap dispensers.
 Arduino and Raspberry Pi Compatibility:
- IR sensors are often compatible with microcontroller platforms like Arduino and Raspberry Pi, making them accessible for hobbyists and DIY projects.
- Libraries and code examples are readily available for interfacing IR sensors with these platforms.
Calibration and Environmental Factors:
- IR sensors may require calibration for specific applications, as their sensitivity and response can be affected by factors like ambient temperature and humidity.
- Reflective surfaces and the color of objects can also impact the sensor’s performance.
