I made this circuit to sense the fluids drops that falls through the silicon tube of an iv infusion pump ,but I don't know what are the suitable photodiode and transistor to use ,please can you help me to get the proper componenets that matches ,
for example some phototransistors are not sensitive to some bandwidths of infrared light ,and many other problems that i don't want to encounter because i have no time to waste ,i have to complete my senior design as soon as possible.
Use something already packaged like this:
I guess a nevermind is in order. I just noticed you're probably using the photodetector to detect the falling drop.
Yes, I figured that out but after I posted. These are integrated packages but have the slot exposed where the droplet can fall through.
