So... Acetronics
*your XL was perfect for make me understand many things!
After a lot of experiment and according to your very usefull XL I finally decide to two different senarios
Acording to your XL (and 10 , 12 and 14 bit results attached to xl file below)
the 'resolution' is at 10bit -> around 8m, 12bit -> around 2m and 14bit -> around <1m
So I am thinking of
1st. just use simple pic 10 bit adc and Darrel's oversampling method (thank you scalerobotics for the link)
2nd use an LM385 for example dual amp and take just 'a window' od the mesurements of MPX4115 between 0-2300 meters
3rd compine LM385 and MAX187 (12bit) to get better resoloution
My onle concern is that as I want to keep pcb at minimum of costs / and parts count if Darrel oversampling method works , it would be Great!
I let you know.
I am in the progress of schematic and pcb design BUT I have to decide the method first!!
