I want to find out if water is flowing through a pipe, based on the vibrations on the pipe. Will a vibration detector and this arduino nano help me (arduino dummy)?

Madhu, it is fairly easy to interface a vibration sensor to a nano using the analog inputs, though I admit I have not used vibration sensors. See this link: http://www.learningaboutelectronics.com/Articles/Vibration-detector-circuit.php. The detector is available from Digi-key and Sparkfun. The nano has the same analog inputs as the Arduino. What I don't know is if the vibration sensor is sensitive enough to detect water vibrating the pipe. You may need to use an amplifier between the sensor and the nano. See fro example the circuits in the manual on this page: https://www.sparkfun.com/products/9196. You may just have to try it and see. You could start with the sensor and try looking at its output with and oscilloscope to see how strong the signal is when the water is flowing. Good luck!

I'd say that this is more along the lines of a 'generally specific' more so than a 'literally specific' measurement. I'm sure you can find the right reading given enough time. This uses displacement to gauge the proof of a liquid so you'll have to be sure to let the hydrometer be free from the edges of its container and the water must be completely still. So yes, it will differentiate but you'll have to have a really good eye for it!

Afraid not. It's a simple circuit connected by water. So it's either on or off. It's fairly sensitive.

Yes, if you can be sure that the water will never be sudsy. If there are suds, they can form a "bridge" between the sensor and discharge pipe from the pit that will keep the sensor triggered even though the water may completely pumped out. A better solution would be the HC5000 Sewage Pump Switch, which is designed specifically for these types of applications.

This device is actually a motion sensor that runs on +5vdc (can be supplied by the Raspberry Pi or Arduino). When motion is detected it can give a logic level "HI" pulse output back to the host, signaling the presence of motion. There are a couple of jumpers and adjustable potentiometers on the card that I assume can be used for sensitivity, I have not tried to figure them out yet. I use my device to signal motion at the top and bottom of my staircase and the output then turns on in sequence the LED strip lights that are on each stair tread to light up the stairs. If going down the one at the top turns them on and then once at the bottom the bottom sensor turns them off. Reverse the sequence if at the bottom of the stairs and going up.

Yes. The flow switch turns on the coordinator when it senses water flowing through the pipe.

I think you would want something a little more sophisticated with a pancake tube. The Inspector or PRM 8000. This is a great little detector but you need something more sensitive and quicker. You would need to bucket some water then test it over a bit of time. Either of the units mentioned will measure over time.

I don't think this has the capability and I am not sure it actually does accurately measures the waves I bought it for. I need to work with its little. More so let us hope. Someone with experience an help.Joe C.

The system has a floating sensor that will trig when water level drop about 1/4 if an inch .The only problem with this ATO it's that make sure that float sensor it's free of algae, salt or any calcium deposit .

It could be used for measuring pressure ONLY if it is a low pressure you are wanting to measure. I do not think you could measure the flow of water with it.

No, it just measures conductivity and displays the results as total dissolved solids. Pure water does not conduct electricity and will read zero TDS. My tap water reads 130 and after the RO filter it reads 002.

Definitely cannot be used direct in water. You can use Aeon Labs water sensor which has a probe on the end of wire and can be kept inside while the device is on dry area. In addition, Aeon sensor indicates lack of water as well.while enire

It is not possible to answer the question unless you have a similar situation. Most times users attach the device directly to the spigot which is not under water. For me the device works fine. The cost is so little just buy one and find out!

You do have to be pretty close to the wire for the sensor to pick it up, so I don't think it would detect it at all underground. Besides that, even if it could, it's not designed to clarify where an abrupt end to a signal is, so if you lost the signal, it could mean the wire is broke or you are no longer following the wire. Bottom line, this tool is not the way to resolve your problem.

Yes, that is correct. While air is flowing it will not read accurate ascending pressure readings, but as soon as you stop the flow it reads very accurate, from my experience.

The needle moves according to how much 'electric current' flows through the metal wand. Essentially, water is the conductive substance. If the soil is dry, no ions can pass anywhere and the needle will not move, so it is dry. The more water, the easier for ions to pass and that makes the meter get its' power. This is more than adequate accuracy for plants. If this were ultracritical and you needed a specific readout of the percentage of water, etc. this isn't the unit. For everything else, it is a winner.

Yes, Scalewatcher works better on PVC than on metal pipes, please read more details here aquagenesisusa.com
