Arduino-Controlled Greenhouse

Post by Rubinia »

Hi everybody, i'm trying to build up a little greenhouse controlled by arduino. Can you help me to write down a complete list of parts?
I mean, I have to control:

- temperature sensor
- humydity sensor
- ph sensor
- a fan
- a water pump
- led strips for illumination.
- CO2 sensor

Which Arduino should I buy? I already have the water pump (which works at 5 V), the fan (5 V) and pH sensor.
I also have the xbee radios series 1 to let the greenhouse communicate wirelessly with my mac. Anyway, the problem that seems to be unsolvable for me is the wiring scheme of all parts.

Thanks and sorry for my confusing topic

You will have to decide which device you plan to use for a controller before you can wire things up. You also need to know how your sensors communicate and what they require in the way of power. If you provide links to the parts you have and requirements for those you don't perhaps people here can help.

You're right.
Here are some links of products I've decided to use (and some of them i already have)

Temp & Hum sensor: https://www.adafruit.com/products/246
pH probe: https://www.sparkfun.com/products/10972
water pump: http://it.rs-online.com/web/p/pompe-ges ... e/0480194/
fan: http://www.jamicon.com/spec/DC/KF0420-01.pdf
CO2 sensor: http://www.parallax.com/Portals/0/Downl ... asheet.pdf
Luminosity sensor: http://www.adafruit.com/products/439
LED strip: http://www.adafruit.com/products/306
Wireless: https://www.sparkfun.com/products/8664 + https://www.sparkfun.com/products/8471

Actually, I've also bought some Arduino Lilypads with relative sensors, but I don't think I'm gonna use them.

Hope someone can help me.

Thanks in advance

Rectification: I've found an all-in-one sensor which is able to sense CO2, Temp & Hum.

The link: http://www.gassensing.co.uk/product/cozir-ambient/

I would prefer to use it because I have to insert it in the growth chamber of the greenhouse, while the controller will be placed in a box under it.

Thanks

The temp and humidity are derived from a sensiron chip on the OPTIONAL CO2 sensor so you might as well go with the descrete units.

When deciding on which arduino to get, look at how many pins you need, how much memory (SRAM and flash) you will need for your program and if you plan on getting shields, make sure to check that they don't conflict with each other (use same pins for example). I just started an arduino project for making automated windows and have similar sensors as you and these are some of the problems I ran into.

Thank you for the reply. I was paying attention to this issue, but my biggest problem right now is the power managemenet and consuption of all sensors/actuators of the system.
All products I've listed are all down in V, but current needed rises up with all the devices I'd like to control!I'm quite sure that an external power supply is necessary and I'm looking for the wall outlet for power.
What do you think? Is it possible?
Any other advice?

try http://arduino.cc/forum/index.php/topic,91467.0.html

they done a great little lib that hooks the cozir right up no problem, i wish i could do the graphs like the guy did
