your help please,
I am trying to find IR LED and receiver for my electronic board for back scattering measurement (measuring sludge concentration). I am looking of 950 nm wavelength for the emitter and below 100 mA consuming current.
my board has 4 pins out, Vcc, GND, signal out for Emitter and signal in for detector.
so i need your help for choosing the best that meet my board requirements, and also a lens that i can use also the sensor will be in pipe line in the sludge.
Thank you very much and i am looking forward to hear from you.
