Ultrasonic Sensor

Hi, I have built the ultrasonic sensor ranger with the help of

but it is not working.

Explanation of the sensor:

Base on the availability of the component I choose,

( I )

1. ICM7555 instead of TLC555
2. CA3130 instead of CA5160 and
3. LM567.
4. PIEZO ULTRASONIC SENSOR: Module T40-1601

R40-1601, Center Frequency:

( I I )

1. Since the reset pin is remain high after given power on transmitter module, I am adding 10k resistance between ground and reset pin.

1. At 5 volt supply [after step ( I I ) . 1 ] to the reset pin, it is generating ultrasonic sound. (Test cond: make CT capacitor value dauble of the transmitter, now this will generate nearly 20khz frequency. This range can be tested on multimeter audible frequency tester.)

( I I I )

Nothing happed on receiving end.

Please take look in this issue, and tell me the possible way to solve it.

Thanks
