Hello, all.
I am doing a project in which I need to measure DC voltage up to 40V. I know that I could do a simple voltmeter using 2 resistors and a capacitor. However, I was looking to buy one module that could measure the voltage of this circuit since I am not experienced in this field. Do you know any type of product that can measure dc voltages up to 40 V. I have found the ZMPT101B but that is suited for AC. Or do you advise me to build a divider?
Thanks.
I found this for you.
I think you should just build one if you can’t find. I checked also but was AC.
I think this based on resistor I want a sensor that I can rely on for long term uses, any ideas?
The Ina series
they mesure current and voltage
or ezshunt if you want
I didn’t understand can you explain more
