Orange current sensor

Post by frater »

I recently noticed these and they were almost the same as I was planning to make it for my own openXsensor.

I already bought several 100A sensors (unidirectional) and was planning to connect these in the same way to the openXsensor that is currently doing GPS and imu.

I have yet to determine how I connect the current sensor to the Arduino board. But it might be interesting to use the same pins. Does anyone know what they (Orange) use?

I think they use an analog input which I could attach to one of the analog inputs of the Arduino. I was also quite charmed by Tempo's idea to use a 16-bit ADC.
Or is 10 bit more than enough for these big currents?

After I receive that Orange Current sensor I will know if that connector is a JST 1mm or a JST 1.25mm
Would that be a good choice for my standard analog sensor input on openXsensor?

I'm also thinking of soldering such a sensor (not the Orange, but the current sensor) directly on the ESC which saves the hassle of a XT60 connector.

Better yet... give it a a dual analog output.
Volts and Current.'

And another question...
The voltage for S-Port is the same voltage as RxBat.
Shouldn't I give this current sensor a stabilized 3.3V voltage?
I already have these.

Or is this an occasion to start with i2c-sensors?

The Orange sensor board is now as cheap as a DIY.

This HK sensor has his own voltage regulator.
The specification says that input voltage should be greater or equal to 3.7.
This allows the voltage regulator to do his job.
So it seems me better to pwer it up with the Rx voltage.

If you power it up with 3.3 volt, it would be better to by pass the internal voltage regulator.
