Wifi water pressure sensor/sender?

[ning]

I was tending to my birds this morning, filling up a duckling *ahem* kiddie pool for the young ducks & geese, and I noted in passing that while I had a decent (but not impressive) amount of water flowing, there wasn't much pressure. Oh well.

Luckily my next morning chore spot was letting out my grown ducks & geese, and I'm like "...... is that water I hear?" lucky for me, the problem was two trees away where a plastic drip hose connector had ruptured and was dumping water. Quick fix.

Realized, though, that a water pressure sensor could alert me to something like this, because I try to "intelligently" balance my watering so in pretty much any line there should still be enough pressure to operate drip - 20-25psi. If I had a sensor that could alert me if the pressure got below, say 10psi, I could be like "oh crap something's spilling".

I recently bought some convenient wifi connected temperature sensors that you stick in a deep freeze (guess why I suddenly bought these, and yes it had something to do with a GFCI outlet kicking the bucket). There's a ~4mm x 30mm cylinder that goes in the freezer or fridge, connected by a long thin ribbon cable, with a wifi sender at the end of that. I get an alert every time someone goes in the deep freeze! But I also get told about a minute later that temperature is good again (I can set the alert temp; I have it pretty low still because if I get an alert that it's melted that's no good right? how about "hey nobody's home but the freezer is at 10F, you've got a few hours to get home and plug it in somewhere else).

I'm hoping for something similar - the maker of my temperature units doesn't have one - for water pressure. It could be something I put into a T, or stick on a hose bib left open, or whatever. Wifi, though, is kinda key here.

Ideas?

Google “pressure switch 10 psi no”.

It will likely show oil pressure switches but they will also work with water.

The key is Wifi here.

Here's something close - it's bluetooth, which doesn't go far enough, but it's the right idea: https://www.amazon.com/Transducers-Direct-Pressure-Bluetooth-Transducer/dp/B07XBVHKG9

If I got really smart, something like a a flow meter (eg https://www.amazon.com/GRODIA-Sensor-Food-Grade-Flowmeter-Counter/dp/B07MY5ZN3Z/ -- not wifi) would probably be better than a pressure sensor, but I'd have to know how much I'm supposed to be using at any given time. Difficulty would be that my pressure tank isn't by the pump, and there's usage not only after the pressure tank but before it as well, so while a flow meter could guard after the tank, the before part would be a problem.

I think I'll stick with the pressure sensor concept for now... if I can find it.

Do you have power where you want to do the pressure sensing? Would this work?

It seems to me that you could have a flow meter for awhile and figure out what the minimum sustained flow is and set an alert for flow more than Y minutes.

WiFi uses a lot more power than Bluetooth or zigbee, relatively speaking, which means power.

Could you park a Bluetooth to WiFi transceiver close enough for the Bluetooth to work?

I like your little flow meter. Arduino/raspberry pi time? Are you up to a little hacking adding a 0-5V pressure sensor to a small arduino?

I like the idea of using a flow meter best, but the topology of my irrigation system is complicated - see here's the pump... and there are irrigation lines that are connected to the system right near the pump. In the other direction there's the pressure tank a few hundred feet away. Most irrigation is beyond the pressure tank... but there's also this funky large line that Y's off before the pressure tank that goes way up the hill... and at the top of the hill connects to lines that come from the other side of the pressure tank. So, there's no good place for a flow sensor that would actually detect leakage.

If I was smart, perhaps I'd move the pressure tank over to where the holding tank & pump are, and so everything would be 'after' the pressure tank; then a flow meter could do that job. The tank currently is where it is because ... well it was there when I moved here, and there's a garden shed there that protects it from the worst cold that we get here. If I built a shed by the holding tank & pump, I'd get that topology cleaned up, and also gain always-on power at that end of the property. Cool, but other than making the flow meter work, it's a lot of effort without a burning need at the moment.

I have the background to do arduino stuff, just haven't ever taken the plunge into that in particular. I probably should.
A pressure sensor here or there would probably be the easiest route as everywhere that I'm concerned with should stay "reasonably pressurized" unless I'm refilling a pond or something (ie max flow, which will ultimately lead to lower pressure), and I can adjust alarms for that sort of schedule.

Go to amazon and look up YOLINK. They have some amazing wifi sensors and switches. In not sure if they have a pressure alarm, but i use their freezer, water leak, remote switches, etc. they link together, so have control 600’ from hub. I can turn on my block heater from a restaurant in town if I decide i need to move snow when i get home.

I have a Wifi switch (breaker) that turns my pump on and off from my phone and moisture sensors strategically placed throughout the house that connect to the Wifi switch that can also shut the pump off. But a small leak anywhere else in the system is hard to detect. With a small leak the pressure will always be between 40 and 60 as the pump has a 40/60 pressure switch. Only large breaks would drop the pressure below 40 so a pressure sensor could be of value.

But if we are just protecting from a large break in the line that causes low pressure, a simple FSG2 switch with the M4 low pressure cut off lever on the side is an easy, inexpensive, and dependable way to shut the pump off on low pressure. I also use an electronic pressure switch that has a low pressure kill at 10 PSI. Electronic Pressure Switch

Then I can see from my phone that the pump is not running as there is no activity (watts) on the Wifi switch.

Since many of you are familiar with mods and customising of cars I wanted to ask you if there is such a thing as a wireless oil pressure and/or temperature sender.

I want a real oil pressure gauge in my car and I'm also interested in knowing the current oil temp.
I'm not particularly experienced with modding and tuning, especially with electronics but most importantly I don't want any irreversible modifications like drilling holes into the dash (and the firewall) for some oddly looking after market gauges. Also the idea of this forums user Soraja isn't really for me since it requires to basically destroy the original fake OPG and afaik the instrument cluster can't be just borrowed from any other NC but is individual to each car.

So I thought a wireless solution sending data to the phone would be perfect. The problem is I haven't found anything like that so far. Can it be that in 2019 there is no wireless sensor/sender at all?
