I think my power sensor is faulty, my spare shows reasonable outputs.
It did give the reading of 260Amps the first time I plugged it in and that might be reasonable for an analog signal of 3,7V.
Then navigator seem fine, but maybe it is damaged now.
There is nowhere in the software where I can get the analog input reading on the current pin?
I can do a reasonable calibration but the Battery monitor in Vehicle setup/ Overview doesn’t move in correlation to the analog input. But I haven’t managed to draw a lot of amps either, but some tenths of an amp…
From the technical details on the Navigator product page, the power sense input pins expect a maximum of 3.3V, so if you know that’s been exceeded then it’s quite possible the corresponding ADC pin has been fried and can’t measure correctly anymore
Not really, at the moment, outside of just setting the battery monitor scale and offset values to 1 and 0 respectively.
Hi guys -
You may be able to read directly from the analog input via lua script - I’ve had success doing this with both a load cell and simple switch… the gcs.send_text will report the raw value scaled to voltage I believe. The 6.6V ADC breakout on the Navigator uses a voltage-divider set of resistors to double the input voltage range, at the expense of resolution…
But if the 3.3V input pin has had 3.7V on it, I agree it is likely damaged
There is some documentation of the successor of this Power sensor, it is supposed to have an inbuilt stop, so it is not possibly to exceed the 3,3V.
I saw how you set up a second power sensor in a different thread Elliot. I will try that when I get connectors for it. Maybe one can re-route the damaged pin to another connector, I will look into that.
I should have a spare Navigator, but they are out of order for the moment.
That script thing, maybe when I get better known with the system. Cool feature though!
