The article presents the results of development of automated monitoring systems for defects and damages of building structures. The first is the "System for monitoring the state of cracks and joints of buildings and structures," this system allows to automatically control the width of crack opening on construction structures. The system has one or more sensors and a recording device in the form of a personal computer, the receiving radio module of the recording system over the radio channel is connected to each sensor and requests measure-ment results. The following describes the upgrade of the system sensor, the new sensor al-lows to measure humidity and ambient temperature and to build dependencies of crack open-ing width on weather conditions. The next sensor is mesdose to measure the stress in the ground of the base, based on the electrochemical principle of action. Mesdose allows to carry out dynamic tests of soils at the same time technical result is achieved in improvement of device reliability and measurement reliability. The last is the mechanical measurement sen-sor, which is also based on the electrochemical principle of operation. Invention is aimed at solving the problem of improving reliability and reliability of converting dynamic mechani-cal values into an electric signal in a wide range of loads and frequencies.
