I'm using accelerometer ADXL203 (https://www.electro-tech-online.com/custompdfs/2012/10/ADXL103_203.pdf) and it's working in a way I don't understand.
I thought it was going to measure in fact how much acceleration it takes but it looks to work more as if it were some sort of inclination sensor (if the accelerometer is totally paralell to the desk shown on video (in 30092012.zip) it gives the equivalent to what would the zero g bas shown on datasheet.
But I want to measure acceleration and by checking the datasheet I get even more confused, it says it measures mV/g so I guess it should in fact be measuring acceleration on its own, which is something that clearly doesn't do, as if I keep the accelerometer quiet in a certain position it stays there.
It's not that big of a deal that it doesn't measure acceleration directly as long as I can know the difference between the initial position and the one it's later as time can be calculated on code rather easily, but... I'd need to know how the output variates according to the position, and I just don't see it on datasheet and I don't think it would make much good to try to measure it as it seems to change with very little movement.
Regards.
