hellofor the IR sensor what is the output voltage in dark condition?if R2 is around 10k and then what would be the output voltage in dark conditions?please help...thanks
If you want a formula, someone more math aware than I am can probably give you one if you (as Soren would say) eliminate the adjective and provide some numbers.
I have one doubtin light conditions the transistor's resistance is less so we get low voltage
but since we have used the resistance R2 higher than the resistance of the transistor in dark condition how would we get the output close to maximum?
or would would be somewhere close to half of Vcc(i.e. 5V)?
