RPM measuring using proximity sensor

[kranthi88]

Hi,
I need to install one RPM Display for my machine. Can anyone help me to do this project.

RPM need to display ( display size 200 mm X 300 mm)

RPM cout signal is proximity sensor.

Have you selected a board and a display yet?

You can also use an infrared sensor

Your smartphone has the capability to be a tachometer as a spectrum analyzer.

Can you please post data/specs of your sensor?
What model Arduino are you using?

Thanks.. Tom...

Count the pulses from a (appropriately chosen) sensor in unit time to determine RPM. Apply a smoothing algorithm to the results to minimise visible jitter.
Start by writing "Hello World" to your display then attempt to detect pulses from your sensor as the machine turns.
In principle it is a quite straightforward project.

RPM cout signal is proximity sensor.

Are you going to sell the millions of proximity sensors that come out of the signal?

Hi Jim,
i didnt select.

can you please help me to select the board, code and display (display should be 300mm X 150mm minimum)

@kranthi88

(display should be 300mm X 150mm

That is a big display, most used with Arduinos are much much smaller.
Not sure I could recommend anything.

Well, if you displaying RPM only (let's say max 5 digits) then maybe a simple LED display would suit. Have a look at this current thread:

Creating 32x126 Display with MAX7219 for Time Display (Arduino MEGA + RTC)

Hello everyone, I am working on a college project where I need to create a 32x126 dot matrix display using 4-in-1 MAX7219 dot matrix modules (16 modules in total). The goal is to display the current time on the display using an Arduino MEGA and an RTC module (e.g., DS3231 or DS1307). But for now i have tried to make a double stack using 2 displays and UNO but the display is showing random lights If anyone could share: Connection diagrams. Sample code or relevant resources. Tips for t…

Hi, @kranthi88

What machine?
What environment?

Thanks.. Tom.

Hi Tom,
Its printing machine, need to fix one proximity sensor for small bolt. based on the proximity signal speed should be display.

thats the project.

[TomGeorge]

Hi,
What is the proximity sensor, part number?
Can you please post a link to data/spec?

Is it an inductive sensor?

What is the speed range.

Google;

arduino tacho

There are many, many designs, just look for the simplest ones that use readily available parts.

Tom..

Do you really need a display that big?
