Re: URINAL SENSOR
Hi for all,
finaly I made some urinal sensor, work fine,
IR transmiter is based on NE555, working on 38 KHz, power supply is 6 V=,
IR receiver is based on TSOP1738, the main problem with TSOP1738 is this,
with no IR signal on them, output pin give 5V, with IR signal on, voltage drop only abouth 1V,
this condition is solved with offered schematics,
Distance between reciever and transmiter is abouth 1 meter, with perfect alignment,
I attached both sch,
Best regards
p.s. I attached also one microcontrolled based urinal sensor, but I do not use them, my version is too cheaper,...
If somebody have a question please mail me.
