  3. ACS709 Current Sensor Carrier -75A to +75A POLOLU-2199 Pololu Australia

    ACS709 Current Sensor Carrier -75A to +75A

    SKU: POLOLU-2199
    This board is a simple carrier of Allegro’s ±75A ACS709 Hall effect-based linear current sensor with overcurrent fault output, which offers a low-resistance (~1.1 mΩ) current path and electrical isolation up to 2.1 kV RMS. The sensor has optimized accuracy for currents from -37.5 A to 37.5 A, and the analog voltage output is linear for current magnitudes up to 75 A. The ratiometric output voltage is centered at VCC/2 and has a typical error of ±2%. It operates from 3 V to 5.5 V, so it can interface directly to both 3.3 V and 5 V systems. Learn More

  5. Non-Invasive Current Sensor - 30A SEN-11005 Sparkfun Australia

    Non-Invasive Current Sensor - 30A

    SKU: SEN-11005
    This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor. Learn More

  6. LTC4150 Coulomb Counter Breakout BOB-12052 Sparkfun Australia

    LTC4150 Coulomb Counter Breakout

    SKU: BOB-12052
    Odometers are extremely useful for cars, they tell you how far you have gone, wouldn’t it be nice if you were able to have a device that does the same for electrical current? The LTC4150 Coulomb Counter Breakout is here to be your odometer for current. If you are wondering: a coulomb is defind as, to put it simply, one amp for one second. This breakout is capable of constantly monitoring the current your sensor is using, is able to add it up, and will give you a pulse each time a given amount of amp-hours have been used. When used effectively and if you start with a full battery, you’ll always know exactly how much of it is left! Learn More

  7. Low Current Sensor Breakout - ACS712 SEN-08883 Sparkfun Australia

    Low Current Sensor Breakout - ACS712

    SKU: SEN-08883
    This current sensor gives precise current measurement for both AC and DC signals. These are good sensors for metering and measuring overall power consumption of systems. The ACS712 current sensor measures up to 5A of DC or AC current. We added an opamp gain stage for more sensitive current measurements. By adjusting the gain (from 4.27 to 47) you can measure very small currents. Learn More

  8. AttoPilot Voltage and Current Sense Breakout - 180A SEN-10644 Sparkfun Australia

    AttoPilot Voltage and Current Sense Breakout - 180A

    SKU: SEN-10644
    This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel shunt resistors, then converted to a final analog voltage output by the TI INA-169. Voltage sense is accomplished by scaling to 3.3V ADC range by a precision resistor divider. Learn More
