Frequently asked questions
How do I read the module with a microcontroller?
Connect the analog output to an ADC input. Make sure the ADC reference voltage suits the module's output range, and set the output with its adjustment before calibrating your readings.
Can it measure voltages above 250 V?
No. The listing specifies a measurement range of less than 250 V AC. Mains wiring is hazardous, so keep the input connections insulated and enclosed.
