I need assistance for a simple project. I am measuring a power source that provides 5 volts and 3 amps to a rechargeable battery. I will be using the current sensor - ACS 712 and the Voltage sensor that can measure up to 25 volts. I need to do this simultaneously. I just learned series and parallel circuits and may be overthinking this.
I'm a novice, so apologies for any incoherence.
I've taken a picture of my setup, and my issue is properly wiring the two sensors. As I understand it, a parallel circuit has voltage the same throughout, while a series circuit has the current the same throughout. So with this thinking, I don't know how to wire my instruments properly to do just that. Here is the current layout, the breadboard is simply housing the sensors. Hopefully I've uploaded the image properly. First time making a post.
Can anyone help me to understand what I may need to do. Am I on the right track? I've connect the power source as well as the recharging device directly to the voltage sensor, but don't know where to go from there. I believe I have also properly connected the sensors to the Uno board.
Here is a written diagram. I'm new to this, so it may still be improper. Thank you for your guidance
Look at the INA219 - it can sense current and voltage at the same time. Modules available from Adafruit, Sparkfun, Amazon etc. I used it to monitor a battery - you can see charging and discharging by the change in sign of the current.
I'm not sure how that would interface while the power source is charging a rechargeable battery. At this time, these are the sensors I must use. If your device can do both, then I should be able to wire it using two sensors. The problem is when charging a battery at the same time.
Thanks for posting the hand drawn diagram. It is a good effort but reveals major problems, if it correctly represents what you have put together.
Neither the mysterious "voltage sensor" nor the current sensor is wired correctly. The current sensor has no input, which must be connected between the power supply and the battery. Post a link to the voltage sensor product page, so we can see how it should be wired.
You need to wire up, test, and fully understand how each sensor works before combining them in one project.
The INA series of voltage+current sensors mentioned above is vastly superior, and Adafruit has excellent tutorials on how to wire and use them.
Finally, what sort of rechargeable battery is this? All rechargeable batteries require a charge controller.
You are on the correct track, asking before frying parts. You will have it figured out and it will probably work the next time you try. The Arduino is a great first (UNO) computer learning device.
When you get time and want to learn CAD (Computer Aided Design) take a look at KiCad, A lot of us use for schematic capture through the Gerber files needed to upload to make a circuit board. The price is free you just download it. I use the Linux version there are many other versions available as well.
