Digital dual axis SCA100T inclinometer project
Inclinometers are used to measure angles of inclination of an object. Angles are measured in reference to gravity. In this project angle is measured by using dual axis SCA100T MEMS sensor. Digital inclinometer is far more precise than manual with bubble in liquid. Author didn’t provide full working code, but he gives SCA100T inclinometer library to use in new design. As SCA100T connects to microcontroller via SPI interface there shouldn’t be a problem at all.

What are MEMS ?
Term MEMS stands for micro-electro-mechanical system, that’s the technology of the very small. It is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate through microfabrication technology. MEMS devices are used everywhere today including automotive, industrial even computer hard drives have MEMS sensors for shock protection.
Ability to integrate mechanical sensors inside chip made possible to design compact accelerometers, gyroscopes, pressure sensors, sensors with integrated RF, and many more. Also technology enables to integrate more than one sensor inside the chip. One of examples may be 3-axis accelerometers. Major producer of inertial MEMS is Analog Devices which produces accelerometers and gyroscopes.
