i`m newbie in electronic world, and i need help with my assigment
i used that kind of circuit for my final project, i used that ir-led+phototransistor circuit for sense a dust particle (pm10 particle category)
i want the particle reflect the ir from led when it pass in front of that sensor,i deisgn the sensor like this
is it possible for me if i used that circuit and that design??
wheter that circuit can only be used as a switch?? because i need this circuit for measurement with high sensitivity
i need the output from that phototransistor to design driver for that circuit before i connect it to microprocessor
