How to control the water pressure

Hi All,

I am laying the basic of my smart garden. I have 2 waterlines going to my garden (1 line on both sides of the garden).

I bought a electronic ventile (https://aliexpi.com/03ty) to controll the water that is going through a mist hose but that hose is getting the full water pressure (about 2 to 4 bar) so I wonder, how can I controll that ?

So basically comes from the main water pipe, through that ventile and then I guess through some other device so I can use that to control how much water goes through.

Hope my guestion is clear and hope that someone can piont me in the right direction what I have to make/buy…

thanks in advance.

Basically, for pressure measuring I would use something like this sensor:


esp8266 and esphome.
For flow measuring I would use something like this:

Thanks, that helps allot… Using that electronic ventile is still needed or does any of these devices also do that ?

You will need ventile/valve. It acts as actuator. Its performance will be controlled by sensor and in that way you will get closed loop automation.
Glad if I helped.

Hi, stil a question… with that pressure transducer sensor can I control the water pressure or is it just for measuring the water pressure?

If it’s the last one, I need an electronic device that can manipulate the water pressure that is coming from my main waterpipe.
