Ir Sensor Technology
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Infrared (IR) sensor technology involves devices that detect and measure infrared radiation emitted by objects. These sensors are widely used in various applications such as motion detection, remote controls, temperature sensing, thermal imaging, and obstacle detection in robotics. By converting IR signals into electrical signals, they enable machines and systems to interpret environmental cues based on heat signatures and emitted infrared energy.
