Adafruit INA260 High or Low Side Voltage, Current, Power Sensor
US$16.15
This breakout board may well be the last current sensing solution you ever need to buy. Not only can it do the work of two multimeters, but it can do it with amazing precision and flexibility. With it you can measure high or low side DC current, the bus voltage, and have it automatically calculate the power. It can do so over impressive voltage, current, and temperature ranges with better than 1% accuracy, all while delivering the data in an easy to use format over I2C.

AM-113 Current Sensor Breakout Board for Arduino
US$21.95
Current Sensor Breakout Board for Arduino
This is a breakout board that can read current from a wire without having to wire it directly to the controller board. Simply pass the wire through the white hoop which is known as the WCS1700, to start reading the current. The output value is adjust by the LM393 which is sent to the microcontroller via Digital on Dout or analog via Aout. This board requires 5v to power the board and can read up to 3Amps.

MOD-MAX471-GY 3A Rated Current Sensor for Arduino Microcontrollers
US$3.84
Do you have a project that requires current sensing, running off a battery and want to know how much mAh battery pack you want to order? This product will essentially help inform you of your current consumption to whatever device you interface with this board with. This product uses a MAX471 Op-Amp to detect current, the MAX471 has an internal 35mΩ current-sense resistor and measures battery currents up to ±3A. This device typically operates from 3V to 36V, and draws less than 100µA while idle. The module is also supplied with 2 screw terminal and 0.1" pitch headers (requires soldering).
