is digital bit-calibration changed, when operated only at 3.3 V?
Thanks for your fast feedback. I know FS3000 is the follow-up product, designed for VDD=3.3 V.
But I still have mounted the "old" FS1015-1015 in my windchannel-experiment in my university-lab and tested it runnnig at only VDD=3.3 V to avoid I2C-level-shifter:I measured the analog output signal, that is LOWER (0.45....2.x V) - I guess because it might come direct from an internal opamp wheatstone-bridge,operated than also only at 3.3 V.
Yes,my question was:
After internal ADC signal conversion: is the digital signal output (409....3686 bits) still unchanged for the range 0...7.23 m/s, even if one applies only VDD=3.3 V, because the ADC's reference voltage might be unchanged? Or, is that calibration no longer valid, if one deviates from VDD=5 V? The I would have to change over to FS3000-1015.
Thanks for your engagement.
Hello again,
Sorry but the sensor won't work and operate if you supply 3.3V as VDD.
If it is a requirement of your system and you do not have any pin with 5V voltage select to use the FS3000 which works with 3.3V.
Best Regards,
