This paper presents the design, implementation, and test stages of a low-cost inclinometer system. The main block consists of the MEMS-based two-axis inclinometer sensor, custom-designed isolated data acquisition circuit, Raspberry Pi single board computer with open-source Python-based software, and remote FTP server. The selection of hardware components, and the algorithm of software are given in detail. Results of system verification, noise characterization, temperature dependency
