@/acs712-20a-ac-current-sensor
Reads current value from the ACS712_20A sensor
PORTport
Board port number the sensor is connected to.
AREFnumber
Analog voltage reference, i.e., the voltage level corresponding to the 1.0 value of an analog read. Usually 5 or 3.3 volts matching the board power voltage
FRQnumber
AC frequency. The number of cycles per second in an alternating current sine wave
UPDpulse
Triggers new sensor read
ERRpulse
Fires if update failed. E.g. `PORT` is not an ADC port.
DONEpulse
Fires on reading complete
Anumber
A momentary current value in amperes
