This article concerns the study of a measuring instrument controlled by ESP 32 with local monitoring of biological parameters providing information on the state of scarring of human skin with 2nd degree burns; A brief review of the literature on existing or deployed therapeutic techniques and means for people suffering from 2nd degree burns is presented and allowed us to study the characteristics that led to the establishment of an architecture of the new proposed biomedical instrument. This electronic instrument consists of: a dimensional sensor (depth and thickness) of the wound; a sensor for humidity and thermal states (hypothermia and hyperthermia); a cardiac parameter acquisition sensor, a microcontroller mini-card which manages the A / D conversion and digital processing of measured biological quantities, with monitoring of these quantities on an LCD display. The virtual simulation results with a functional aspect obtained are validated in the PROTEUS software of said instrument, which are presented and then interpreted, prove to be satisfactory; the experimental workshop and the main results obtained are presented. These give very good results since in addition to the completely stable acquisition of biological parameters, the proposed system does not interfere with devices emitting electromagnetic radiation. Thus, a first prototype of this proposed instrument was produced, with a view to embedding it in a new biomedical therapeutic suit for people with 2nd degree burns.
