Reading ac mains current with sen0211 with adc mcp3008

[Nicolas6316]

Hi im using current sensor sen0211 for energy monitoring, i have connected it to the mcp3008 and the code works fine cause i have tried it on ldr, but on the current sensor it doesnt work. Can someone pls help me i deeply appriciate the help

You have told us nothing about how you are reading the sensor. Mine requires some additional circuitry to create a signal that ADCs can read. A sketch of your circuitry would help. Those sensors are simply a transformer and they output AC as you would expect. The AC needs rectification, smoothing and a load/scaling and the actual accuracy depends on your circuit and or calibration steps.Mine also has an extra wire that seems to be independent of the transformer. The documentation from the mfgr is virtually useless.

I've recently completed a project using the SCT-013-000 sensors.

After weeks of trying to read the sensors using a raspberry pi and an mcp3008 (also an MCP3424 ) I gave up and used an arduino nano clone (about $2). The Nano was working within hours using simple code. I then connected the Nano to the Pi over serial.

I was able to lift the same code on to a Wemos D1 Mini (about $4) and build another standalone monitor doing away with the Pi

I used the guides on the Open energy Monitor site
