Ammeter click (Go to Parent Category)

Ammeter click Ammeter click is a mikroBUS add-on board with circuitry for measuring electric current (both AC and DC).

Two onboard screw terminals (probe+ and probe-) are bringing in the current, which then passes through a shunt resistor. A voltage proportional to the strength of the current is generated accross the resistor. This voltage passes through an amplifier before it's fed into a 12-bit ADC which then outputs a digital value through the mikroBUS SPI interface.

The firmware processes the digital value to determine the exact amperage between 1mA and 1A for DC current. It's also possible to measure AC current by deriving the value from peak to peak measurements. At the same time, the voltage can be directly monitored through the AN pin.

The board uses either a 3.3V or 5V power supply (it's important not to power the board from the same power source you wish to measure).
