What is the best way to do this project?

[mongol]

Hello guys,
How can I do this project?

I need to use this fan: https://www.arctic.de/en/P12-PWM-PST/ACFAN00170A
With an infrared sensor that can read temperature from about 15 cm. I found this:

https://protosupplies.com/product/gy-906-mlx90614-non-contact-precision-thermometer-module/

Everything needs to be battery powered.
Then I power on with a switch, an LCD should show the temperature and the fan starts, and a red led is lit.
When temperature is below certain degrees the fan should stop, the led should be green and a buzzer should sound.

What components do I need for this and what battery? I would prefer a rechargable powerbank if possible but I don’t know what specifications I need.

Thank you.

What are the best components for this?

"Best" depends on your skills and budget.

You need any Arduino board for development. For the final build a Pro Mini or ATtiny should do, any standard LCD display, and a sufficiently strong battery.

This cab be done without any microcontroller.

How long do you require the device to run for on a single charge?

Not if he wants to use the MLX90614.

I would love that, but How? Because the temperature sensor must be infrared (to read temperature from a distance of 15 cm).

About 2 minutes.

Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frustrating for you and frustrating for us.

What are you checking the temperature of with a contactless thermometer?

Can you please tell us your electronics, programming, arduino, hardware experience?

Is it possible to attach an infrared sensor to this relay?

Hi,

@mongol

Is it possible to attach an infrared sensor to this relay ?

This unit has what looks like a resistive thermistor input, it will not interface with your sensor module.

Can you please tell us your electronics, programming, arduino, hardware experience?

Thanks.. Tom...

Thank you,
I have no experience, that’s why I search online in order to learn how to do it.
