Why I love NRF-PPK2! a new affordable kit to measure very small currents

День тому

I recently discovered this kit (Power Profiler Kit II) by Nordic Semiconductor to measure very low uA currents for my battery based sensors. It comes in a very attractive price point. In this video, I will set it up and do a quick demo on a PIR sensor.

Thanks for such a great and informative video about our Power Profiler Kit II.

To check the accuracy, simply add a resistor between VOUT and GND. Apply for example 3V over a 10k resistor, and see what you get ;)

@benargee Рік тому

Yeah but you need a precision voltmeter to verify voltage and to verify resistance tolerance. Voltage and resistance have to be almost absolute for the current measurement to be as good.

@@benargee define accurate. It's all depending on the applications requirements, and this is a 100usd kit ;)

@@wlgrd7052 I guess I'm saying it's good to know the error tolerance of the voltage and resistance so that the error of the current measurement can be known.

@@benargee of course, if that is what you need.

With PPK2, when using as an ammeter mode, am I correct to assume it would act as a multimeter/current meter? Where I could measure the inline current of a wire at any point of the circuit as long as the wires will be connected in series in Vin / Vout of the PPK2? I plan to measure and test a few signal currents coming in / out of an IC.

I have mine ordered, but i'm waiting for it to be in stock, these things seem to be sold out in all eshops in my country.

@MrDIYca 2 роки тому

They do! I just checked digikey and it is sold out.

It's a very popular product. You can see the availability for the Power Profiler Kit II on our website: www.nordicsemi.com/About-us/BuyOnline?search_token=nRF-PPK2
