IR sensor RPM - Sensors - Arduino Forum

· I bought an Arduino Mega 2560, a 5’’ TFT Display with SSD1963 controller board and an IR sensor MH Sensor series. Firstly, I would like to program the micro-controller without display and turbines. I build provisionally a wheel and I try to do the program for just measuring the rotational speed with the IR sensor. I saw in other forum topics some program to do that, but ... IR sensor RPM ...

Digital Tachometer with Arduino for measuring RPM ...

· In this circuit, the IR sensor module is interfaced with Arduino to estimate fan rotation speed in RPM. The calculation is done as follows. After 5 seconds Arduino measures RPM for a minute using the given formula. RPM= Count x 12 for single object rotating body. But here we describe this project using a fan which was rated 9V/100mA. So the formula will be: RPM…

Best Sensor for RPM counting. - Sensors - Arduino Forum

· I am very new to building electronic stuffs because of our school project. i am building a 3 bladed fan with motor controlled via arduino but i need to read the RPM of the fan. I tried using infrared sensors but it does not work as expected and give random readings but was able to detect if the blade of the fan is passing. I am now thinking of using Hall effect sensor to count the RPM.

Arduino based RPM counter with a new and faster algorithm ...

This project is developed from scratch as an attempt to measure the exact RPM (Rotations per Minute)value of various motors using a single IR sensor, an Arduino board and an essential key ingredient -a Laser Pointer(necessarily Red).. This project uses the fact that the IR sensor also reads the the low number of IR radiations given off by the red laser.

Rpm counter IR tachometer - Help needed - Sensors ...

· Hello, From this code posted above for the rpm sensor can anyone explain the line : rpm = 30*1000/(millis() - timeold)*rpmcount; From what I have gathered 'rpmcount' will be the number of interrupts, '(millis() - timeold)' the time duration between the rpm value updating and '30*1000' derived from having two two interrupts per revolution.

How to use IR sensor with Arduino? (With full code ...

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board.

arduino - Wheel encoder using an IR sensor - Electrical ...

I made a rotary encoder using a IR sensor and a wheel with printed black and white spokes. Everything seems to work but I'm wondering if there is a better way to code this. The IR signal looks ideally like a square wave and I have it looking for the rising edge of each wave. Then calculate the time between rising edges to calculate the wheel's RPM. int wheelPin = 11; // I/O pin for encoder int ...
