The main objective of this project is to avoid physical contact between the motor shaft and tachometer by using a non-contact tachometer in order to make it convinient, while measuring the speed of aBLDC motor.Also using standard contact type tachometer may not feasible in some applications.
The proposed system uses a arduino and a rectified-power supply. An IR transmitter and a photodiode is connected to the controller for measuring the speed of the BLDC motor. A LCD display is interfaced to the arduino controller for displaying the speed information.
This project uses IR light reflection principles. A white patch is mounted on the shaft of the motor. A pair of sensors (Transmitter and receiver) are used to develop a pulse for each reflection that sends an interrupt to the arduino controller. The timer of the controller calculates each pulse received in a particular time intervaland displays the same as RPM (speed) on theLCD display.
The concept of the contact-less tachometer can be enhanced and implemented in the bikes, cars for speed measurement.And thus, the usage of the traditional analog speedometer could be avoided in future.
Arduino based tachometer system for the good price for the engineering projects. It is very comparative engineering project. It is very good BE final year electrical project and Diploma projects in the electrical student is use. This project electrical departments students in final year is use. For the last year engineering project for the electrical departments student is use this project is IR sensor based project.
Arduino based tachometer for this project is the arduino at mega 328 based and ir sensor based project for the good project, excellent project for the BE last year engineering student is use for the student is use and electrical student is use. This project for the competitive project in the BE electrical sensor based project last year engineering student for the electrical student in last year engineering student in the use. This project is the arduino based project
The engineering projects give in the ELECTROSAL HI- TECH PVT.LTD. The best place of the degree and diploma final year engineering projects as well as electrical student is use
Arduino based tachometer it is the best projects for the electrical base in final year student is use and idea for the and electrical degree and diploma base students and 100% output is done.
