The object - digital electronic fix the basic parameters of the environment "clothes-man." Purpose - an experimental model of portable electronic device to fix the basic parameters of the "clothes-man" based on microcontroller technology. Methods - systematic analysis, synthesis, prototyping and computer modeling. Digital technique and technology intensively enters all the spheres of human activity, and it is difficult to do without modern technologies even in ordinary (home) life. Ten years ago, it was hard to imagine the result of using the usual mobile phone. Today, this device can already be attributed to the multifunctional mini computing system. And by right it is called "a smart phone". Regarding the latter, this idea has already been successfully used in the field of "smart house". This allows to improve the quality and comfort of human living space much more, and moreover, to save the consumption of energy here, which will lead to preservation of the ecological situation. A further aspect of human activity is clothes. Here, the new digital technologies are introduced not so actively. This is due to several reasons. And one of the component parts of such a situation is the relatively weak presence of efficient, and at the same time energy low-consumption microcontrollers on the market. Recently, however, a new generation of microcontrollers has been presented by some leading companies who could easily pretend to be used as base ones for devices in the field of "smart clothes". The authors have reviewed the microcontrollers of Texas Instruments company, which due to its circuitry and the parameters are suitable in this field of application. This measuring system consists of the following parts: sensors with strain gauges and pressure sensors combined two temperature-humidity. Due to the fact that the resistive-gage sensors for their connection circuit of the bridge was used. Sensors are divided into two groups and provided, from a digital-to-analog converters (DAC). This allows a very wide range to adjust their sensitivity. The signal from each bridge reaches by amplifier with variable gain (PGA), and then input analog-to-digital converter (ADC - TI ADS1263). The microcontrollers of Texas Instruments MSP430 series should be considered one of the most energy-efficient solutions in the field of embedded microcontrollers. They are specially designed for applications with ultra-low power. They have a flexible clocking system, some low-power modes, the ability to instantly switch to the active mode and intelligent autonomous peripherals, allowing to achieve ultra-low consumption and increase the battery life greatly.
