From sensor to data, this demonstration of 10BASE-T1L SPE walks through an actual use case from the deep depths of the SparkFun basement.
Vibration sensors aren't really telling you what you really want to know. A current sensor on each of the pump power lines would give you better information on the status of the pumps and motors. You could tell if/when they are operating, as well as how much current they are pulling (to determine if they need maintenance, replacement, or the output pipe is clogged). A couple float switches would tell you the water level of when the pumps should be operating and when the water is about to flood the basement.
With just 6 extra wires, two power supplies, and separate I2C cables you too can have single pair ethernet
Excellent Idea Sparkfun with the sumps! We have a similar water table issue. We will likely do something similar to ensure the sumps are always running. One thing to consider (in terms of efficiency) is to make sure the sumps are clean of silt debre at the intakes, so you are not paying more for the pumps working harder. Should be yearly checked depending on iron levels in water, silt, calcium, etc. excellent video!
Lot of criticism in the comments, but I still appreciate the video. Ever since I saw one of Nick's (I think?) videos about this years and years ago, I've been idly thinking about ways to monitor sump pumps, so it's nice to see options.
I don’t quite understand how running single pair to the basement is any easier than normal Ethernet ?
I'm not sure what problem single pair ethernet solves in this situation regular ethernet wouldn't. If you used POE you would have battery backed power from your network/server closet. And used a small Arduino or even a PI with some sort of water level sensor in addition to your pump monitors.
Very interesting stuff, thank for sharing!
I think it's funny that you monitor whether the pumps are running by an accelerometer, rather than just monitoring the pumps themselves.
You should use a sonic distance sensor to measure water level.
Nifty and I'll read up on the single pair ethernet stuff. (curious what the distance spec. is)
So you are basically monitoring that the pump output pipes are vibrating but not really that the pumps are pumping enough to keep the sump below a critical level. It would seem to more important to monitor the level in the sump instead of the vibration of the pump output. Vibration doesn't necessarily mean pumping at a rate to keep the sump low enough.
This feels like the wrong way (very naive) to monitor pumps. Volts, Amps, Flow, Pressure - with connectivity to (or outright replacement of) the control system for the pumps.
Why not send power down to the basement over the other Ethernet pairs.
Interesting but I don't see the purpose of using single-pair ethernet only to convert back to normal ethernet. It seems like an unnecessary conversion. Why wasn't normal ethernet used from the basement all the way up? If I were to design such a system I think I'd prefer to know when the pumps were running electrically versus by vibrations. I'm curious if an employee went to the basement and shook those pipes would you get false readings upstairs? It is interesting to see these devices really used versus the countless videos of knobs controlling LEDs on someone's table. Thanks for sharing.
A real demo would've actually shown us how this is useful when needing to exceed the 100 meter limit of ethernet without the need to use fiber but instead we got a marketing video that just shows how much they can overcomplicate this project.
sound is awfull
