Hi Rainer
What I do is that switch the power to silected sensor only I do it by using
FET. since there is not enough power for all sensors.
so when you switch to sensor 2 other sensors are kept off.
there is enough power for one sensor since my circuit takes only 500 microAmp.
which is around 4%of total power.
I have more details ( see in specification/ some no that can give you idea
of power) on www.geocities.com/mindsensors
and I am composing more on circuit to add. once that is done I will put it up

| (...) Hi Nitin, okay, I see. Sorry, but then your circuit isn't interesting for me. I thought about using Sharp GP2D12 with it, but that won't work. First the Sharps have a current consumption of about 33mA up to 50mA max. Second the Sharps need (...) (23 years ago, 20-Mar-01, to lugnet.robotics.rcx)

| (...) Hi Nitin, if you do NOT need an external battery, how much current (with which voltage) does your multiplexer provide for each active input ? Very interested, Rainer (23 years ago, 19-Mar-01, to lugnet.robotics.rcx)
