Not that with this low cost approach the burden voltage is (with the Fluke multimeter) 10 times lower than with a uCurrent Gold. I have another multimeter, an OWAN B35T where the burden voltage is 20 times lower.
Recently I received this Expert RF Powermeter from Russia.
The device was sealed in shrink foil and send in a plastic container together with 2 attenuators and a pigtail cable.
You can use this tool to check if nodes are transmitting and to obtain an indication of the transmission power of these nodes.
The RF Powermeter has different, fixed measuring frequencies and it is possible to view the transmission signal in what’s called the “Fill Mode”. In addition, other measurement settings are also possible (see specs in link below)
Power output RN2483 (Microchip mote)
You can switch the readout in mW or dBm. Unfortunately, the value in the display is only visible for a short period of time during the transmission, so during the measurement you should pay attention and watch the screen.
Power output ESP32 Heltec node
10dBm?? I have measured several Paxcounters … some came to 8 mW.
There is a new alternative called tinyCurrent with some nice enhancements like BNC connector and possibility to increase the dynamic range by up to factor three.
With just a CR2032 battery you can double the range by tweaking the voltage divider’s ratio – 1.5V vs. 3.0V.
When you hook up an external power source with 5.5V (possible through the JST connector) then you can actually achieve factor 3.66 – 1.5V vs. 2.75V.
Bonus: you can overdrive the thing for up to 6.5V or even more (voiding warranty)
Oh I found the tool, watched the tutorial, however from what I understand it is for Nordic products only and you need a profiler kit board, etc. RAK5205 is basically RAK811 (STM32L). So that is the part I do not understand. How are they using the software with a hardware that seems to bot be supported. Again probably a noob question.
No it isn’t. Read the specs carefully before buying. Specifically the voltage and power ranges. Then look at what is required to use it. (Next look for another solution )
