A ten minute look at the INA219 current sensor, hooked up to an Arduino Uno, measuring the current flow from a battery to a bulb. Part of my 18650 current monitoring project.

Excellent! I'm trying to measure the current using an INA 219, but I'm using a PWM board, as I need to dim an LED strip, but I'm not having success, even connecting the GND of my NANO to the PWM board's power input (-). Any tips?
It's great how your video from 5 years ago can demonstrate just what I needed to see today. I really appreciate this!
What's that blue putty-like stuff you hold the board with when you solder?
Hi Julian,
a few months I am trying to build 3 phase 50 + 50+ 50 amps MPPT.
It is BUCK topology 200 V IN / 100 V OUT / 12 – 24 – 36 – 48 – 72 V / batt
but I have serious problems to monitor precisely
50 amps current per phase, I made BUCK with
AMPLOC 100 A, then ACS758BI 50 A,
but measurement with some filtering is not precise,
with precision, that I need to calculate P @ O and INCREMENTAL COND. algos.
Do you think, that som INA219, INA228, INA229 would be better ?
Or there be similar problem with noise / from FETs switching /.
Also i use 2 ina219 parallel without any pull up resistor
For i2c port🤭
Would you tell me where can i use it for something else
I use it before for sense curent fire detector and make alarm
How to calibrate the INA219 sensor?
I have tested on battery 9v without bulb and the load voltage is 0.9v. it is suppose to get 9v?
Hello Sir. Is the module applicable also to detect current at low side of the voltage? So that it can be applicable over 500V?
Board: I2C / TWI pins
Uno, Ethernet A4 (SDA), A5 (SCL)
Mega2560 20 (SDA), 21 (SCL)
Leonardo 2 (SDA), 3 (SCL)
Due 20 (SDA), 21 (SCL), SDA1, SCL1
It would help if you included in your video which ports on the arduino uno are scl, sda.
Thanks for the trick with the Bluetack, ta!
Awesome video!
I am trying to make an ammeter to monitor battery voltage draw on my motorcycle. Would this set up work for that? How would you go about making one on oled?
Hi! It will work if instead of a battery I will use a microgenerator with an output voltage varying between 0 -15 volts?
