Current

Finding out how much current your project is drawing can be incredibly important whether it's a wearable, portable project, or just to watch the power consumption.

Non-Invasive Current Sensor - 30A
SKU: SEN-11005 Brand: Sparkfun

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.

ACS711EX Current Sensor Carrier -31A to +31A

Rating:
100% of 100

1 Review

SKU: POLOLU-2453 Brand: Pololu

This board is a simple carrier of Allegro’s ±31 A ACS711 Hall effect-based linear current sensor with overcurrent fault output, which offers a low-resistance (~0.6 mΩ) current path and electrical isolation up to 100 V. This version accepts a bidirectional current input with a magnitude up to 31 A and outputs a proportional analog voltage centered at Vcc/2 with a typical error of ±4%. It operates from 3 V to 5.5 V, so it can interface directly to both 3.3 V and 5 V systems.

LTC4150 Coulomb Counter Breakout
SKU: BOB-12052 Brand: Sparkfun

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!
