Controlling 24/12V Low flow high pressure pump using any Arduino UNO and relay module for a misting system

Projects General Guidance

Hey guys, I am planning to create an automatic misting system for my plants using an Arduino Uno, A 24/12 V DC Pneumatic low flow high pressure pump (meant to work with misting nozzles, since high pressure is needed to push water through) and a DC relay module to control the pump.

That is my basic strategy, however I would like to know your thoughts on this approach.

I will have to automate the pump to be turned on and off after a certain interval of time. So what approach should you guys think, i should take ? Should I add a clock module or just go with a simple wait command and then loop.

Has anyone ever done such a project ? Any suggestions you guys would like to make. Would love to learn from your experiences.

EDIT: thanks a lot, guys. The community here is really wholesome and the replies till now have been really helpful <3

Will you start the misting manually by pushing a button or do want something automatic based on the time of day?

Will the OP be adding humidity sensors to turn off on mister with a given humidity level?

I'd use an ESP32.

I've done a mist humidifier and run an automated plant grow system.

Hi. Nice project, I would love to see the apparatus in place!

With a "wait", you can schedule periodic misting, so could be an ideal solution. But blind from time if I may.
With an RTC module (simple to setup and configure with arduino and numerous library), you can access very fine scheduling!

Drop the relay and use a logic level N channel MOSFET transistor instead. Relays have a limited life a d don't click forever.

Hello varun2004

This is a nice project to get started.

Keep it simple and stupid firstly.
Run some tutorials for the hardware selected.
If you are happy with the results of the tutorials you can merge these to your project.

Have a nice day and enjoy coding in C++.

Sir, it's like it has to be misting 24x 7 after a regular interval, since the environment's pretty arid here.

Thank you ! I have had experience with coding Arduino in the past for school projects, this is the first time i will be doing it for myself!

good luck and have fun.

Oh, thank you sir for this information. It will be really really essential since it has to click on/off forever.

Thank you ! Will there be an inherent advantage of using esp ?

12

I think so.

I suspected/felt that....

I'm an UNO guy..... Use whatever controller You at hand!
As a stand alone system it will be fine. If You need to communicate with remote devices other controllers might be favourable.

Then you will need a clock module like this;

OR a DS3231 module
