Below10w Issue with 12-Channel AC Current Monitor with I2C Interface

Software Python
1

Hi

We recently purchases AC current monitor with I2C interface
(12 channel 20 amp i2c current sensor board with Arduino Leonardo
https://store.ncd.io/product/12-channel-on-board-95-accuracy-ac-current-monitor-with-i2c-interface/)

Connecting with a raspberry pi 4 its working fine with Monitor, Fan
but

The lights do not return voltage power. Always shows 0
Do products below 10w need any code?

Thanks in advance

whats the operating voltage of the 10W lights ?
it only reads AC current.

Thanks

Hi

Operating voltage is 220V
(its holder type bulb , Not AC DC converter)

and
we are getting almost 3 times more Amps for the equipments which we can measure.
Ex :
Code return 0.302,
Clamp meter : 0.1

Code return 0.615,
Clamp meter : 0.19

Please let me know if we need to update any calculations

Thanks in advance

Hi,
is this a inductive device or resistive device ?

You can calibrate the sensor to match meter.
The calibration commands can be found on the product manual…
Thanks
