Question: Will the sensor be suitable for measuring the voltage from a 3-phase generator with 0-30V? I need to have galvanic isolation from the Arduino, so I cant use a regular voltage divider after rectification
Answer: Unfortunately, this module does not provide galvanic isolation. MCP6002, provides an analog RMS signal of AC voltage, but without isolation - the chip divides and amplifies the voltage, but does not galvanically separate it from the Arduino.
