Hello,
I’m looking for a sensor I can connect to Arduino that will measure the power through a higher voltage line (110 or 220V) and return results in such a way that I can read them on an Arduino (either though Analog, I2c, serial, etc…).
I’ve not gotten far with google, as the keywords intersect with many irrelevant results (low power sensors, or results on the power consomption of sensors, etc…)
Hi KMN.
The only sensor we currently carry that can measure current on a 110/220 volt power line is our [Non-Invasive Current Sensor. Keep in mind this is just a sensor and doesn’t include the additional circuitry that you’d need to connect it to an Arduino and get readings from it though.
The link below might be helpful for more information on how to connect this sensor to an Arduino.

Thank you Chris !
The non-invasive sensor looks great, the désavantages are its size, the audio jack connection (although something I can cut) and the fact that it requires additional components (capacitors and resistors).
But the ACS723 (https://learn.sparkfun.com/tutorials/cu … 1566840605) looks like a good candidate. The only question now is whether can I hook it up to a 220V line knowing for certain I’m always une 5 Amps. What do you think ?
Hi KMN.
The boards we put the ACS723 chips on are not designed for 110/220 volts. We do not recommend using these with line voltage applications.
