Видел когда-то в интернете статью, где делали инклинометр на базе двухосевого акселерометра ( или двух одноосных ). Собсно найти теперь не могу. Нашел только как можно сделать на базе одного акселерометра, но это не то. Может кто-нибудь видел или ссылку знает?
Compact, Dual-Axis Tilt Sensor is accurate to 0.1 degree.(Analog Devices Makes Industry's Most Accurate, Easy-to-Use Tilt Sensor 100 Times Smaller than Available Solutions)(Company overview)
Offered in 9.2 x 9.2 x 3.9 mm laminate-based LGA package, ADIS16209 programmable MEMS inclinometer provides fully compensated direct angle output. It measures dual-axis tilt with less than 0.1[degrees] linear inclination error across [+ or -]30[degrees] range when mounted horizontally and also supports vertically mounted single-axis implementation over 360[degrees] range. Along with SPI port, features include 12-bit auxiliary ADC input and DAC output, digital self-test, and configurable condition monitoring.
