SCT013 Split-core Current Transformer Non-invasive Sensor AC 100A 50MA Split Core with ADS1115 +Audio Cable Female+10PIN Male and Female Dupont Wire

For anyone wondering, what I received IS a ADS1115 (Tested 2 boards) with proper 15 bit resolution.One thing you need to remember is, this is a differential ADC with a Sign bit, so instead of 16 bits at 65536 it will be +/- 32768 at 15 bits. So far everything has been working great including Current Transformers, no issues at all with accuracy.

These sensors and board struggle to stay connected to the board. I have to reset the micro controller every minute or so. There isn't any reliability where I can use the sensor to monitor anything in real time.

This kit comes with just about everything you need for a remote arduino based power monitoring. This style of setup using the SCT013 has it's appeal in low cost and compatibility but you should spend 2 or 3 more dollars and get the PZEM-004T. It does everything this does better, you also get voltage, power factor and some onboard memory. The biggest reason is the other model comes calibrated from the factory so no fine tuning the watts/amperage with this kit via code. you don't even need the ADC on the other one as it's built into it. Using ESPHome and a Wemos D1 Mini really couldn't have been much simpler.The reason I took a star off is only because the CT clamp is just a little bit smaller and doesn't fit around the main lines in my panel which are 4/0 I believe and the other clamps does.

Excellent.

This is a great little kit for sensing alternating current amperage and sending it to your Arduino. Apparently, you can also sense voltage if you wire it differently, but I have not tried that since that is not what I purchased this for. This kit includes both the non-invasive clamp-on style sensor and the tiny circuit board which converts the analog signal into serial data. You can also wire your own circuit if you know what you're doing to read and analog amperage through one of your Arduino analog pins. You do need to do a little bit of soldering and such on the included circuit board, but if you're into working with Arduino projects then you're probably used to that. Overall I am very happy with this product and I will be purchasing more of them now that I know it works to complete my smart home project.
