Re: High(er) resolution current sensor

Hi carbo, Just for information after using few 100a and 50a acs 758 without ads1115 we found out that the slope is linear (good), but the zero is not 2.5v it can change from a sensor to another and the resolution is less than what we can read in the datasheet (bad) it also varies from a sensor to an...

openxsensor locator

Hi mstrens,

Is it possible to send altitude by the locator, we have the project to use one on a model with no telemetry, in fact we want that the tug plane pilot drop the sailplane when the altitude is 150m.
thanks

Re: graupner mx16 hott

thanks mstrens for your answer i was modifying my message as the same time you answered, there is a current sensor too in this config, for me it's not the problem, there is perhaps a radio configuration to do, i don't use a hott radio either i discover this radio today! the telemetry smartbox brings...

Re: MPVX7002 air speed sensor

I've just finished to build it, i see in the sketch that we can use ppm to change from ms5611 to airspeed compasated and for each choice, we can modify sensitivity (ms5611 case) and compasation between ms5611 and mpx7002 (airspeed compasated case) if i use it, i have to program a switch 3 positions ...

Re: two current sensors on one arduino

thanks mstrens it is what i thought, there is only one current sensor parameter in config advanced.A friend want to put a 7a with 30a so he needs two openxsensor on his smartport receiver to do the job.

Re: current sensor

thanks for your help now it is really clear for me i will use vcc 5v and no divider to get a better resolution with lipo. if i use nimh i can use a divider to compensate the discharge curve. Now i understand why the value are in homs or khoms. When i use your program I've got 1.43v with20k and 8k it...

Re: current sensor

It is to use it with a ACS712 5A in a 5v arduino whith 1.1v selected. with a 10kohm and a 47kohm. I will get #define RESISTOR_TO_GROUND_FOR_CURRENT 47000 // put as comment or set to 0 if no divider is used #define RESISTOR_TO_CURRENT_SENSOR 10000 // put as comment or set to 0 if no divider is used o...
