hc sr04 module is there with me.

one person extracted the Tx and Rx elements so that transmitter element can be fed with 40khz from 555

reciever is fed to a vu level meter .

his demo shows led levels without Microcontroller usage.


Question:
if we remove the module..will there be false trigger and cause problem?
