Hallo, I need to design an array of ultrasonic sensors for measuring distances of objects, but I'm lack of some basic knowledge about sensors. Could somebody help me please.
I want to use 2 transmitters, but I dont know what would be the return echo at a receiver if the receiver receives both of the two reflected signals due to the 2 transmitters.
And as far as I know, we can get the Time of Flight by using the function pulseIn(). But is that function only dedicated for PING sensors, or it is also able to be used for other distance ultrasonic sensors ?
Thanks very much.
