Measurement Of Speed Using Photoelectric Pickup

Measurement Of Speed Using Photoelectric Pickup

Speed measurement by photoelectric ( optical ) transducer is a convient method, since many type of photon devices are available.  In present set up a photo diode is used as transducer. A photo diode ( in reverse bias mode ) is a device the  resistance of which falls to great extent when it is exposed to light  radiation.In actual we must describe the system before the transducer.  A light emitting diode and a photo diode is mounted in such way that  full radiated energy falls upon the diode.


  • Speed measurement using photo electric pickup transducer can be done using this kit.
  • On-board RPM meter for measurement of speed
