40KHZ Ultrasonic Parking Sensor Open TypeStructureTransmitter And Receiver Split
Description:
The open type ultrasonic sensor always be used in pairs,one is used to transmit ultrasonic waves,another is used to receive them.
it's used for various detections.For example,in measuring distance aplication,high S.P.L.
But as a attention it cannot be used in outdoor applications because they are open type structure,
and it also cannot be used for automotive application.
