Description: Schematic diagram of the ultrasonic receiver and then the first ceramic capacitors at both ends so no need to enhance the signal, but do not have a strong anti-interference. My approach is the expense of anti-jamming and increase the distance Oh, no way can only be the case. Another note is sent to and received from the probe was 8 cm! ! Way to ensure the distance measurement, I do a good job close to the range distance is 6 meters. Send and receive the distance between the probe may also be smaller, but not less than 4cm (online said), I had the time spacing ranging from 2cm to about 3 meters
