It measures distance by emitting a sound wave of a specific frequency and listening to the bounce of that sound wave. The distance between the sonar sensor and the object can be calculated by recording the time elapsed between the generation of the sound wave and the bounce of the sound waveWorking Voltage 5V DCQuiescent current less than 2mARanging Distance2cm 450 cmHigh precision 0.3 cmEffectual Angle 15Test mode Test distance Duration of high levelSonic 340ms2 MORE DETAILS asin B0B1MJJLJP bestsellersrank 15,280 in Industrial Scientific See Top 100 in Industrial Scientific 1 in Ultrasonic Proximity Sensors datefirstavailable March 4, 2022 itemmodelnumber HCSR04 itemweight 1.06 ounces manufacturer WWZMDiB packagedimensions 3.62 x 3.62 x 0.67 inches
