Hello all - I'm new to the forum, but have been looking into Arduino for various projects I have in mind so I'll most likely be fairly active on the forum once I get going.
This is the first project I am in the process of planning, but I would like some advice on whether or not the concept is viable.
I am a sufferer of a neurological illness (I'm not going to discuss my illness here) and as such I rely on medical marijuana as pain relief (which is completely legal in my country). I grow my own marijuana at home, in a room that I specifically designed and created for this purpose.
There are a number of things I'd like to automate within my grow room - I'd like to know whether or not an Arduino would be up to the tasks in hand.
Requirements of project
Have a real time clock that can be changed via a touchscreen LCD display
Be able to control the turning on / off of lights depending on a timing schedule manually set on the LCD screen. For example - lights on for 18 hours, then turn off for 6 hours, then turn back on for 18 etc. The lights run on 240v
Measure temperature and humidity inside the room and display the results on the LCD screen situated outside the room
Reduce / increase the speed of an intake and extraction fans dependent on the temperature inside the room. For example - the extraction and intake fans are idling constantly for fresh air to enter the room. However, should the temperature inside the room go above a certain threshold the fans should speed up until the temperature has dropped below the threshold, then continue to idle until the temperature rises again
Record the MAX and MIN temperature and humidity readings on a daily basis for later analysis
[u]In addition to the above, I would eventually like to add the following functions to device[/u]
- Record soil moisture
- Activate an irrigation system for a set period of time (eg. 1 minute) once the soil moisture has dropped below a certain threshold
- To detect fire / smoke. In the event of smoke or fire being detected, the device should emit an alarm and also activate a powder smoke extinguisher housed inside the grow room
I have found other similar projects online, however none of them are quite what I need. I've been looking at the Arduino Uno for this project, but I'm unsure as to whether or not it would suffice for the number of tasks I'll eventually need it to execute.
Materials I've identified so far that I'll need;
Arduino microcontroller (not sure which model as yet) Temperature & Humidity sensor module LCD touch screen Real time clock chip SD Card module (inc. sd card) Various wires and other installation bits Smoke detector Extinguisher 240v Relays
All I'm after at this point is some ideas on whether or not this project is viable and if so which Arduino controller should I be looking into?
Any other advice or pointers would be much appreciated.
