Contactless Rotor RPM Measurement using Raspberry Pi and Laser sensor

Manganleiba Oinam Meetei


This paper presents an experimental study of high resolution rotation per minute (RPM) measurement of a rotating shaft using Laser sensor module. A novel method is implemented for measuring low speed as well as a high speed. Experiments are conducted using a raspberry pi which is based on ARM7 processor. The experimented results are presented for low speed as well as high speed separately and also calculated resolutions are shown.
