I find a high pressure pump :http://viewitem.eim.ebay.pt/12V-Volt-Mini-DC-Diaphragm-Water-Pump-65PSI-3Lmin-RV-pump/330893776704/item

the problem is that my misting system only can handle pressures between 220 and 280 kPa... there is some way to reduce the pump pressure?

well... guess I have to get a new pump then... Thanks for the advice!

I found a project similar to mine, the guy use this board: http://viewitem.eim.ebay.pt/UNO-R3-ATMEGA328-ATMEGA16U2-Controller-Board-FOR-ARDUINOs-IDE-Compatible/290901496705/item

and this LCD:

It's a good choice? or there is a better one? I'm trying to save money but don't want something that don't last.

The pressure doesn't depend on the pipe that I use? I'll use a 6mm pipe ...

I have a more powerful pump that pumps 6200 liters per hour and can raise water 5.5 meters. Should be enough right?

A basic arduino like this: http://viewitem.eim.ebay.pt/UNO-R3-ATMEGA328-ATMEGA16U2-Controller-Board-FOR-ARDUINOs-IDE-Compatible/290901496705/item ?  or there is a more basic one?

Concerning the sensors, could I connect them directly to the arlindo board or I need some kind of module?

I was thinking  about using this LCD: http://viewitem.eim.ebay.pt/1602-16x2-Character-LCD-Display-Module-HD44780-Controller-Blue-Blacklight-/170817946781/item

It's cheap but I don't know if gonna last...

The second relay will control the power supply, to run the fans.

I really like the relay ideia, it's seems cheap and efficient. smiley

I'm thinking about using 2 DS18b20 temperature sensors and 2 HS1101 humidity sensors.

Then I need to connect the sensors to 2 relays and one LCD to display the measurements.

What arduino board will I need to do this?

I also think it will be tricky to connect the pump to the computer power supply... If I connected it to a regular plug will I be able to control it?

I just need to control the temperature and the air humidity, ideally the CO2 levels too but not absolutely necessary.

The important is to keep relative humidity above 80% and temp below 21ÂșC.

The mushroom farm will be a 2X4 meters rectangle with 2 meters height.

I will be using this water pump: http://viewitem.eim.ebay.pt/200GPH-Aquarium-Air-Water-Pump-Fish-Tank-Submersible-Pond-Fountain-Powerhead-12WEU230V/310569179711/item?variant0=EU-230V&transId=337425859021   with the EU plug (230V)

I'm currently growing Pleorotus (in bags) and Shitakee (bags and logs)

Hi guys!

So, I'm constructing a mushroom farm and need to be able to control temperature and humidity of the farm.

I'm thinking about using a misting/cooling system and 3 cooling fans.

The cooling fans will be just three 4-pins desktop cooling fans conected to a computer power supply.

The misting/cooling system will be controled by an aquarium water pump with 12W of power.

Can I also connect the water pump in the computer power supply?

If you guys can tell me what kind of board and sensors I need to control these two systems I will be very grateful.
