this type of sensor normaly based on linear hall effect senser and a coil wound around a ferrite or iron core i have some deisn and application note share once back home in evening

well the cheapest one is wire wound around the cable where you want to measure your current

I want to measure AC current. I'm developing a home-use application. I've previously worked with flyback transformers at high frequencies like 3 kHz. I'm not exactly an amateur in this field. What I want is to produce a current-measuring sensor with a minimum cost, up to 30 amps. This might be outside the scope of traditional transformer logic. Who knows? I'm open to your ideas, Sonsivri members.

Sorta looks like a university thesis project, if you were somewhat into electronics you would already know that it is a current transformer with a load built in hence the 1V output.
A split core type is more calculations compared to a non-split. You want help with something let the users on sonsivri do all the guessing and figuring stuff out! |

In what range of current do you want to measure is it AC or DC. I also see you only have two posts. How well are you into the arts of electronics. Just so I can adjust how I/We may help you

If you're familiar with the SCT-013 series sensors, I'd like to build an equivalent sensor myself. How should I proceed? I'd appreciate your advice.

Didn't have any luck with any of these CAD apps. Solid Edge has a free community version. I'm using it now, and the results are quite promising. I am giving up on Fusion 360 after the recent policy changes forced non-commercial users to pay a license fee. I'm not earning a penny using this software. I thought there would be a free edition for enthusiasts, and all of a sudden, the rules have changed. Sorry about the inconvenience, users, you can do whatever you want with the now-useless designs you created over three or so years.

It is normal to assume that different resin types were used on your PCBs. No-clean types can leave a residue when cleaned with IPA. The water content threshold for IPA can be as high as 30%. The so-called pure IPA used in electronics can have a water content of up to 1%. The purer the alcohol, the more prone it is to evaporation. If the cap of the IPA container is left open, the water content may reach approximately 2% after one hour, depending on the humidity and temperature of your room. Each passing hour will add another 1%. That of course, renders it unfit for delicate cleaning as the water content will cause corrosion (oxidation) on metals, and cause contamination, which is unacceptable for RF or High Z circuitry.
