Well some of the previous posts by the OP on this subject have suggested
that they might not be thinking about the problem logically and breaking
it down into manageable chunks. The "headless chicken" approach tends to
mask the subtleties of your post so I thought I would try to focus the
search.

Ah yes, I tried to make him see the light for himself but he appears to

40KHz +/- 1KHz = 39 - 41 KHz.
38.75 KHz is not in that range. Does it work? No. Seems like a good
place to start looking to me.

Hi
Look the resistance R is adjustable, and if I set the value as
R = 23.460410557184750733137829912023
= 23.46
then receiving frequency will be
Frequency = 1/(1.1*R*CT)
= 1/(1.1 x 23.46x10^3 x 0.001x10^-6)
= 38.75x10^3
Will not it works?
Waiting for yours response.

There should be enough light getting through the gap between the
transmitter frequency of 38.75kHz and the receiver at 40kHz +/- 1kHz
for you to be able to see the problem yourself.

Hi,
I have built the ultrasonic sensor ranger with the help of
"2002MAR08_RFD_DA_AN.PDF" 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:
40.0khz, with 1.0 khz variation. Etc.
( 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.
2. At 5 volt supply [after step ( I I ) . 1 ] to the reset pin, it is
generating ultrasonic sound.
(Freq of this sound 38.75 khz, because of tolarance of resistor and
capacitor)
( I I I )
Nothing happed on receiving end.
Please take look in this issue, and tell me the possible way to solve
it.
Thanks
Dibyendu
