Working voltageDC 5V Working current 15mA Working frequency40 kHz Maximum range5m Minimum range2cm Measurement angle15 degrees Trigger- input, pulse 10 μs TTL level Echooutput signal TTL level - PWM duration from 150 μs to infinity if there is no echo. Dimensions (edit)45 * 20 * 15mm Measurement order.
The control device sends a positive pulse with a duration of at least 10 μs to the Trigger input.
At the Echo output, a positive pulse is formed with a duration from 150 μs to infinity. The period of the impulse, the start of the measurement is recommended after 50 ms.
The distance to the obstacle can be calculated using the formula: S=F/58; where S is the distance in centimeters, F is the pulse length in microseconds S=F/148; where S is the distance in inches, F is the pulse length in microseconds
