I'm going to use this with an Arduino to keep a tab on my aquaponics system. Do I need to buy a pH circuit, BNC connector, and analog cables for this?

There are probe to analog boards available on amazon. The probe is basically a high impedence battery. You will need an low impedence opamp circuit to use it.

If you don't like this one I found this on EBAY not to sure if it works or not BUT it might be something people might like to get around GMO http://www.ebay.com/itm/Smart-Garden-Aquaponics-System-Hydroponic-Agricultural-Aquaculture-/111121833855?pt=US_Hydroponics&hash=item19df609f7f... Or just buy a used one and use what ever type of seeds and fertilizers you want...

You only need a male to male BNC adapter. These cables have female BNC on both ends and female coax power on one end with male coax on the other. I was able to hook up two of these plus a 60' to connect to a remote camera and it works just fine. You can buy the BNC adapters in packs of ten here on Amazon

This is an analog field CCTV monitor with a BNC input. POE cameras use an IP interface so there is no way to connect it directly unless the camera has an analog (BNC or TP) output.

Yes, I do aquaponics in mine. I have fish and plants living in it. Should be safe for food and plants.

1). My battery has not run out yet and I've had the unit for a few months now. An LED comes on only when the float registers low water so I don't think it's consuming a lot of power and, as such, I expect the battery to last a long time. 2). This is a nylon wick setup, not a hydroponic setup. It even comes with soil for the pots. 3). As I'm all set up I don't know exactly how much soil or water but the pots are 3" square at the top and taper down a little. Unit holds enough water that over the few months I've had it I've only topped it off twice. I can leave it for weeks at a time without worry :D To be honest, when the battery runs out I probably won't replace it. I find the float that measures the water level gets stuck and needs a tap to fall back to the water level and read accurately. I've just been lifting the pot out and checking the level by eye. I haven't bought a second for this reason. If they offered a low-tech version of this for $20-30 I would buy ten of them. The wicking action is awesome but the electronics suck :P Hope that helps :)

Yes, you need a monitor at minimum and one that can accept BNC plugs, otherwise you will need a converter. For example, if you want to wire it directly to an old LCD computer monitor you will need a BNC-VGA converter. That will allow you to monitor in real time but if you want to view multiple monitors, record, or have remote access via Smartphone, you will need a DVR made for security cameras. I use a Q-See DVR that is made by some company that rebrands for companies like Q-See.

I did. Just need to use a diode between 86 and 85 to keep the volts from killing fish. But I would use delay relay like (SRD-12VDC-SL-C NC Triggered Time Timer Delay Power Relay Module 12V DC). It keeps it from getting into that loop of the bottom of the container to the sump.

I didnt purchase an accompanying box bcs I didn't need one. But you will need a terminal/junction box to mount this. Make sure you have at least 6 inches of slack with your copper when wiring up the box, whether this is an end or continuing point along your circuit. Any other questions, feel free to post.

sorry, i can't help you with the chemical composition. I live on the West Coast near Washington and the water here is almost perfect at 5.5 or 6. You will need very little ( a few drops ) to drive the ph up or down. This product does work. Google " How to change your water's ph " and you will get lots of advice. If your ph is too high or low your plant nutrient food will sediment out and be impossible to be utilized by the plant. I suggest that you get proper hydroponic plant food. I no longer use this product but first step is to find out what your waters ph is.This will help. Good luck. sorry, i can't help you with the chemical composition.

Hi Dan your question seems a little vague but your correct with the wall wort just won't do. You're going to need a few more components and isolation. You may want to look at linear technology such as the lt3573 flyback converter. They have some great circuit diagrams which may be of help. Otherwise unless you elaborate more of what your trying to do I can't answer.

Peter: As I am not a chemist and given the importance of what type of material potable water will be flowing through, I would strongly recommend contacting Gilmour directly. I am sure they would be more than willing to insure your drinking water safety by advising exactly what material the connectors are made of. I can tell you that I own a couple of pair of these fittings and they work flawlessly. I am using them on a 3/4" garden hose into a 3100 psi power washer and to which the added flow has made a significant performance difference. No issues what-so-ever.

Dear Robert,Thank you for your trusting,This is waterproof LED light so normally we install it and connect the cable on the professional circuit board.If there are any thing else I can do for you pls feel free to contact me.Have a nice day! ;-)Grace.

this SSR needs 7.5ma in the input, you should be fine with arduino and RPi setups.

Yes, it has a bnc input. It is essentially an IP camera that sends its data over a coax. A 12 v power supply is required.

You need 2 things for your meter. 1) A bottle storage solution and 2) Bottles of calibration solution. For the storage solution, do a search on Amazon for "electrode storage solution" and buy a bottle of one of the solutions that come up. For the calibration solution, search "pH calibration solution" and buy a bottle of whichever solution you need. If measuring the pH of acidic things, you really only need to get a bottle of 4.01 and 7.00 calibration solutions. If measuring alkaline things, get a bottle of 7.00 and 10.00 solutions.

yes. J. Bobay says same hardware version is required...I got one with an external probe and one (same brand) without. They're both on the same Linux server and provide me graphs and warning pages.I wrote a product review with a few more details and a couple sample graphs.
