Ultrasonics sensors

Sensors work by detecting any variation in environmental factors like light, heat, motion, pressure, and so on. If any such variation is detected, then it is converted to an electrical signal so that other electronic devices can process it. Humans have a diverse hearing frequency ranging from 20Hz to 20KHz. Ultrasonic sensors work with a frequency above 20Khz.
