This device will interface with any microcontroller with an ADC (or multimeter / oscilloscope / voltage measuring device) and report back a voltage
reading when it detects the amount of current being used (or even no current). You do some simple math and can then calculate how much current a device/project is drawing.
If you want to use this with a Raspberry Pi, you can, but you will need an MCP3008 like the one we sell.
1, the current sensor chips: ACS712ELC-30A;
2, pin 5V power supply, on-board power indicator;
3, the module can measure positive and negative 30 amps, analog output 66mV / A;
4, when no current is detected by the output voltage is VCC / 2;
5, PCB board size: 31 (mm) x13 (mm);
Note: ACS712 is based on Hall detection principles, try to avoid using it near any magnetic fields as this may have an impact on your readings/results.
