I have this 4 pin IR sensor LTH 1550-01. Please let me know where can I find a circuit connection for it to be used as IR proximity sensor. I will be using the AtMega 16 Microcontroller.

It basically has a an infrared emitting diode and a NPN sillicon phototransistor mounted side by side on converging optical axis in a black plastic housing. It has got 2 pins to ground, 1 to I/P and 1 to O/P.[/quote][/b]

This is the configuration for QRD1114.. The same is applicable for LTH-1550 too
