So somehow going thru my stuff I found 6 of the FBVS01 voltage sensors .. Looks to me to be a voltage divider (probably wrong ) ...Can i use these to measure voltage with my vario's that I have built ? . I have Ms5611 and gps on my vario's , would like to measure total bat. voltage
Thanks again
Allen

Re: FBVS01 voltage sensor
Yes. The division ratio is 2:1 or 4:1 or 6:1. You can simply use the first number as #define RESISTOR_TO_VOLTAGE and the second number (always 1) as #define RESISTOR_TO_GROUND to get the true voltage displayed. Did not test it, but there is a good chance it will work as described

Re: FBVS01 voltage sensor
Thanks for the reply...So I connect V+ to A0 but do I hook ground to ground or leave it unhooked .
Thanks

Re: FBVS01 voltage sensor
Both ways will work in practice. There is a small risk that the additional GND connection will have to deliver the complete power if the standard GND connection fails. Worst case is burning tracks in RX. So better unhooked.

I will leave ground unhooked...Thank you so much for your help

Re: FBVS01 voltage sensor
So the FBVS01 voltage sensor works fantastic.. It is exact on the radio measured against a watt meter and multimeter .It's actually a little more accurate then the Frsky SP-FLVS sensor .. Took me a bit to configure it , but it is dialed in..Also have the current sensor and the GPS along with the ms5611 and mpu6050 working great ..Thanks again for making it possible to build these .
Thanks
Allen
