I am using ultrasonic receiver for ultrasonic data transmission. The circuit diagram is attached herewith. I am getting peaks when transmitter and receiver are perfectly aligned and 1.5 mteres apart. But with increasing distance, reliability falls. Also there are a lot of false peaks which lead to spurious data values. Can anybody please point out any mistake in the circuit? ( I only have a single ended supply and transmitter circuit is working perfectly as I get peaks even at 2-3m but the data transmission fails. Expected data transmission rate is 100 bytes per second).
