SF-SEN-10643

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 pre...

SF-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 condi...

SF-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 sens...

SF-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...

SF-SEN-09028

This is a small voltage and current sense PCB. DC current is determined by measuring a voltage drop across a pair of parallel 1 mOhm 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 b...

Overview

SF-SEN-12040

The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place...

SF-SEN-15176

The Zio Current and Voltage Sensor is a highly accurate current and power monitor. Utilizing the INA219, it’s able to read DC current and power over I2C with up to 1% precision. This is a great fit for a variety of applications, including estimating battery life, tracking sola...

SF-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 SparkFun Coulomb Counter Breakout is here to be your odometer for current. If you are wond...
