Gravity Analog AC Current Sensor (20A) - AC Signal Conversion Module and Open Type Transformer Probe Included - Non-contact Measurement

It functions but the output is very noisy and the reading jump around wildly. I had to install a wide moving average filter to get it to output something that can be used. Also, not linear.

Been doing some extensive testing with this sensor and I'm not very satisfied with the results. I'll say it measures in the range of 1 to 5 amps ok. But I would not recommend it for measuring less than 1 amp or above 5 amps with any kind of accuracy.

I put a meter on the voltage output of the measurement board. The current measurement isn't linear or at least reliable. If I hadn't tested it first before using it in a circuit, I would have never known.
