Block Diagram Infrared. A ftir uses an interferometer to measure all ir frequencies simultaneously and produces an interferogram2 the interferogram is. Ir sensor ir transmitter ir led photodiode ir receiver light dependent resistor.
It consists of an ir sensor module ir1 transistor bc547 t1 5v single changeover relay rl1 diode 1n4007 d1 led1 mini submersible dc motor pump and a few other components. Ir sensor will produce the high frequency beam which is projected on the photo transistor with the help of 555timer at the transmitter. The ir circuit described below is mainly designed for liquid level detection or proximity detection.
