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). R575  Qty: Add to Basket Price ex. VAT. Est. Weight: 15g.

Hall Current click Hall current click is a high precision current sensor. It carries a galvanically isolated TLI4970-D050T4 miniature magnetic digital current sensor that utilizes the Hall effect to measure electric current. It can detect current levels from -49 to +49 amps, both AC and DC. The board carries two EXTreme ZPower connectors (IP- and IP+) to connect the conductor. The current rail is galvanically isolated from the interface to the microcontroller. The sensor readings are sent to the target board through the mikroBUS SPI (SDO, SCK, and CS) lines. The board uses a 3.3V power supply only. Hall current click can be used with dangerous voltage levels. Use caution when working with current and the Hall current click - DO NOT TOUCH THE BOARD WHILE THE EXTERNAL POWER SUPPLY IS ON! On Special R485  R815  Qty: Add to Basket Price ex. VAT. Est.
