SEN0193 - principle of operation
 Account cancelled  2017-11-09 13:35:12 1662 Views0 Replies I'm trying to understand how this module works(SEN0193 ), from the schematic the 555 runs in astable mode @ around 900khz and 50% duty cycle.I couldn't find the capacitive sensing in the schematic, from visual inspection the capacitive "probe" is located between D1 and R2 - how does it affect the peak detector output?
