4Pro Tx power consumption - Shred - 05-03-2022

I’d love to move my Pro2 over to a system with better radio range, but looking at the specs for the 4Pro transmitter, I see “Average Consumption: 230mA” - and that’s at 12v.

Yegods! Surely there is meant to be decimal point in there?  For those of us running stations on solar power in not so sunny climates, even 23.0mA is a big ask.  I modified my current transmitter to get the power consumption right down.

Did you go for it?  I'm currently perplexing upon the power / panel issue.

Think on this figures, just for the LoRa transmitter on the 4Pro. It send a data packet almost every 2.6 seconds.

   


Plus there is around 100mA for the Nano.
Any sleep mode (while not impossible) wasn't seem practicable, as the Nano need to be always ready to read every pulse that comes from the wind sensor (some will give 8 pulses per rotation), or from the rain gauge, besides reading the wind vane, and control the LoRa radio.

I agree that in not so sunny climates, the best solution may be not using a solar panel, but instead a direct 12V power supply coming from a mains adapter.

Werk, I see.  I will still need to go down a remote PV as the sensors are remote from the house.  It might mean that at certain times the Stn will drop out as it loses power.

No - unless I can run power out to the shed that has the sensors on it. it's not going to happen.

Thanks for the explanation, Werk.  It looks like the Nano is the main problem - and not easy to overcome it.
