    I have made a decent ultrasnic proximity and distance sensor...

    I generate the 40 KHz signal from my micro controller(much better waveforms than a 555).. amplify it using 2n2222 transistor and feed it to the uSonic transmitter..

    For the reciever, I have connected the reciever in the same way as the Leang minison module and connected the output of the comparator to the micro.

    For proximity, I check the out put of the comparator, and for distance I calculate the time of flight between ping generation and recieved ping..

    Thats it

    can u explain this 'Leang minison module'.

    will simple amplification of the signal received at the receiver do the trick???
