current sensor

the sensor is giving too much noise when i measure a dc current of 1A. i have connected a value of 1uf 63v electrolytic capacitor in parallel with 100nf ceramic capacitor. the connection diagram and the oscilloscope output is attached here. the sensor output is for zero current. help me. Murali.

Hello, I'm making a workbench DC power supply monitor, with a current sensor for each voltage source, using LM324 opamps. The sensors work well alone, however they seem to measure not only the current on their source but also the currents on the others, so I can't measure the current on each...
