Hi, I've design my ultrasonic transducer circuit to send and receive signals. I used a 555 timer to generate the pulse for my transmitter circuit, and a 2 stage op-am to amplified the receive signals.
The problem is, I want a circuit to start counting when the signal is sent, and stop counting when the signal is receive by the ultrasonic receiver.
Then after the counter stops counting,I want to design some kind of circuitry to tell the data logger the counter has got a number on it that i want to record...
I'm having problems designing a circuits to give me all those functions.
cheers
