Hai,I tried to read AMPS rating for an induction motor using microcontroller.
Specification of the motor is 230VAC and 1.67A during full speed operation.Checked the current rating with clamp meter also.Its 1.55A to 1.65A reading are observed.
I connected ACS712/5A module across the phase wire to motor and measure the OUTPUT from module.It's showing 370mA as maximum value by selecting mA in multimeter.
I have to interface the module's output to PIC controller to measure the AMPS rating.
So I tried the above OPAMP circuit to amplify the value from module to interface with MCU.But their is no output from the amplifier circuit.It always showing zero value.Without connecting to MCU also showing zero value while checked with multimeter means.
How to solve this issue..?
