SparkFun Hall-Effect Current Sensor Breakout - ACS712
Price: $12.88
Availability: Stocked-NoBackOrder
Sparkfun Item #: BOB-08882 -

"This is a breakout board for the fully integrated Hall Effect based linear ACS712 current sensor. The sensor gives precise current measurement for both AC and DC signals. Thick copper conductor and signal traces allows for survival of the device up to 5 times overcurrent conditions. The ACS712 outputs an analog voltage output signal that varies linearly with sensed current. The device requires 5VDC for VCC and a couple of filter capacitors. Please keep in mind that though the ACS712 is rated...

AttoPilot Voltage and Current Sense Breakout - 180A
Price: $33.36
Availability: Back Order
Sparkfun Item #: 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. The PCB is supplied without leads or connectors. The pad sizes are large enough to accommodate 12 gauge heavy duty leads (see datasheet) but care must be exercised in soldering. Smaller gauge...

Non-Invasive Current Sensor - 30A
Price: $16.58
Availability: Stocked
Sparkfun Item #: 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. This particular current sensor will measure a...
