← Older revision Revision as of 05:24, 21 October 2026 (One intermediate revision by the same user not shown) Line 1: Line 1: Ultrasonic sensors transmit chirps that are generally in the frequency range of 23 kHz to 40 kHz. The frequency is way above the normal audible limit of humans that is 20 kHz; therefore, it is referred to as ultrasonic. Through this chirp, ultrasonic sensors determine how long it takes the chirp to come back after reflection from any object using echolocation technique like bats do.{{Cite web |date=2021-04-01 |title=Ultrasonic Sensors: How They Work, Key Specs, and Applications |url=https://www.sameskydevices.com/blog/the-basics-of-ultrasonic-sensors |access-date=2026-10-21 |website=Same Sky |language=en}} Ultrasonic sensors transmit chirps that are generally in the frequency range of 23 kHz to 40 kHz.
