Sensor, Ultrasonic Distance, high precision HY-SRF05

Choose between 3-unit or 5-unit pack!

Ultrasonic sensors overcome many of the weaknesses of IR sensors - they provide distance measurement regardless of color and lighting of obstacles.

They also provide lower minimum distances and wider angles of detection to guarantee that obstacles are not missed by a narrow sensor beam.

This model is an upgrade from the lower precision HC-SR04. This has 5 pins and can be used in 1-pin trigger/echo or 2-pin.

Use these formulas to calculate distance:

Distance (in cm) = (elapsed time * (340 m/s)) / 50

Distance (in inches) = ((elapsed time * (340 m/s)) / 50) * 0.393701
