The INA219 is a digital device that allows the measurement of current, voltage, and therefore power. Simply, connect wire serial through this device and it will give all the information provided via I2C communication. It is very simple and reliable to use. It has a jumper for making changes to the I2C address so you can connect more than one INA219 to single microcontroller.
The maximum current of the measurement is determined by the shunt resistor found on the plate which is 0.1ohm (± 3.2A). Yes, it can measure the power in both directions! If you want to measure other currents or smaller currents more precisely, check out the datasheet to change that resistor. The maximum voltage that can be measured is 26V.
The digital voltmeter displays connected voltage using 7-segment characters.It contains three figures and measures up to 30V DC with precision of 1%. It is powerd by same wire at which it measures voltage making it easier to connect. On it sides it has two mounting holes.

The Shunt Resistor is a special type of resistor with small resistance which allows large currents to pass through it. This is useful for measuring the current in a circuit: due to the Ohm’s law and voltage drop on the shunt resistor, we can know exactly which current passes through it. For example, for this resistor whose maximum current is 50A, the voltage drop at that current will be exactly 75mV (0.075V). Using a precise ADC, we can accurately measure the current of our consumer or power source.
• Max. current: 50A
• Voltage drop for max. current: 75mV
• Dimensions: 120mm x 25mm

The digital voltmeter and ammeter measures and indicates current and voltage in 7-segment digits! You can connect it to your power source to see your real-time characteristics or a consumer cost to check its consumption at any time. It measures voltages up to 100V and current up to 10A (shunt resistor embedded). This device is intended for installation in a housing.
Do you want to measure a higher current? Not a problem! The device comes with a cable to connect an additional external shunt resistor that will allow you to measure even higher currents. Shunt resistors can also be found in our store.
This small sensor will measure the current that passes through his wire transformer and the information you get in return is in the form of a small stream. That small current will be measured as a voltage drop that is already built into this sensor. The sensor works on the principle of an open transformer. It’s not as complicated as it sounds. For more details, check out the datasheet.
Only one wire put through the hole!
