Photodiode and IR LED set sensor interfaced with PIC16F84A

Postby lloydi12345 » Tue Sep 07, 2010 6:50 pm

Hello.. I'm planning to use the output from the photodiode to generate logic 0 or logic 1 to be taken by a pic16f84a.. But i would like to try it first with a circuit.. Can you give or suggest a simple circuit where there are photodiode, IR LED, and LED (that will light if an obstacle is detected).

Here is the set of my sensors

IE0575HLG Infrared-Emitting Diode (100mA)
PD87BR1 Infrared-Emitting Pin Photo Diode Receiver 150mW

Hope somebody could help.. THanKS!

Is it possible to reverse bias the diode with a suitable resistor and measure voltage across it?

Or look at this
