The control system for my pond filter is dead. I need to build a new system. The filter itself has a lot of buttons and so on, which is not necessary. It uses a 24v water sensor, 24 volt motor (to turn the drum) and 220v to the washing pump. I think i could build something that works, but the pump, and motor needs to run a couple of seconds, after being triggered. So, the 24v sensor activates 220 volt pump, with a 4-5 second delay. The motor runs of a separate 24v supply, and is connected with the wash pump.
OK, is there a question here?
I am assuming you need help but I am not sure what sort of help you need.
Please read the getting the most out of this forum sticky post at the start of each forum section, for how to ask a question here.
Is that 24V AC or DC? MAKE SURE.
Right, i need help with which components to get. And how to build it. I know very little about arduino.
24v DC!
Does that apply to electronics as well? Switching mains is not something a beginner should be attempting, it is dangerous and could be lethal. It is fine saying you will be careful but a beginner doesn't know what they have to be careful about. But water around mains is especially dangerous.
You need to post a link to your sensor so we can see what sort of signal it returns.
Then you need to tell us what sort of current it needs to drive your motor and your drum so we can advise on the relay board you need to use.
Also how often will this switch things on and off so we can tell it using a relay is the best way to switch things.
Right, thanks man. Ill return later today, with info! I know the basics with electronics, i know how to measure voltage, i know how to NOT get killed
