    I haven't tested this sensor yet and I don't really have an application for it where I could use it but for the price I just had to get one of these just to tinker some with it at a later point in time to see how useful it is, one thing that immediately strikes my eye is the super small isolation between the input and ground plane considering that this can be connected directly to live wires with 230 volts on it, personally I wouldn't recommend this to anyone and I certainly wouldn't do that with this particular sensor board. I just got it for testing purposes and wouldn't use it in any other way.

    Today I had the time to create a board with this tiny device and an ESP8266 (also from Banggood :-)). I measured AC power so I had to set up frequent sampling, measure peaks in the sinusoid voltage and conclude to a root-mean-square value. It works like a charm. I connected the low voltage connectors logically, the output went to A0 PIN on ESP. I also connected a 220V phase to the high-voltage part. See photos. Let me note that the high-voltage connector is really weak, use it with care as it is like it's near to fall apart but eventually it does the job.

    Easy to use, small and provide good metrics - I use this device to measure the power/current consumption of the various loads off my 12v solar setup. It provides me with a very good indication of how my 12v battery is fairing.

    We tested this sensor. Perfectly works. Soldering seems like jagged a little bit, but not affects the sensor’ work.

    As Described and Ordered. Intend to use this sensor as part of a LiFe battery capacity tester.
