Current Sensing?

@hek said in Current Sensing?:
BBSP-LPD
Do you have a link for the product on Openevergymonity? Can't find the product you're speaking of.

@hek - Do you think there would be a specific need for a clamp sensor over a LED sensor node? Do you possibly think that people would be clamping individual lines out of their fuse box rather than just wanting to know what the overall usage is?

maybe ot, but for the fun, someone selling iot devices for the electric cupboard, told me once, he had to have an expensive decennial insurance for selling his devices even if it's only connected to the serial protocol and his device is dc.. crazy! hopefully we know what we do :)

@hek if i search in my folder archives, i'm pretty sure to find this :grinning: (because i designed this a while, but never tried this one..). i mean the clamp sensor.
Edit: ah oki the optical one..not done this one, not hard, i let it for you @Samuel235 ;) ive enough projects in progress, and i don't need it though lol -
@Samuel235, I was just looking at the picture :)
An overall pulse sensor is really accurate and useful for whole house consumption.
But clamps also has its applications.
I'm thinking that we could have the Pulse sensor for overall usage and then put clamps onto individual lines that we would want to monitor, such as upstairs lights, downstairs sockets, sheds, cookers. This is my idea rather than compicated nodes such as relay nodes to monitor the current usage. I feel that people don't really want to know how much their bedroom lights are using, they want to know how much energy is being used on all their lights. and then for example if they think its high, they replace all with LED lights. Just an example :)
Do you guys feel the same way or do you like the idea of individual monitoring if it was already built into the node without you having to mess around making the nodes with them on there?
I made my relay module with one on there because as a hardware designer it was interesting to have such, but after doing it and thinking about it, i think it may have been just the theory of implication that was a nice thought and that we wouldn't really care for it in reality....

The boxed pulse sensor with velcro is the perfect solution, but it is darn expensive.
Clamps are a solution, but in order to have power consumption you need also voltage reading and PFC calculation like THIS little project. Imho it is safer to use the pulse sensor :) -

I am about to order some LM393 light sensor modules to test them out, but the real challenge will be to remove the photodiode, add a little cable and find a way to stick it to the pulsing LED
@gohan I already have some designs in my head. I don't think this would be that hard to make from scratch to be honest. I'm aiming to make it look exactly like what we have been looking at with: https://shop.openenergymonitor.com/optical-utility-meter-led-pulse-sensor/

Is everyone's power meter omitting a RED LED flashing, or do some countries have different colours?

@Samuel235 yellowish here
-
@Yveaux - You're still in the rough area of 600nM wavelength, so we're all good for you :)
-
@Samuel235 Great! Surprise me ;-)

too hard to resist, so first draft freshly printed
-
@scalz - I hate being a student and having no time. Beat me to it! Do you have the circuitry sorted?
What 3D modelling software do you use? Fusion, solidworks?
Also, what size have you made that, what size PCB would it accept?
