The key element of the method for determining and monitoring the breathing frequency in Wireless mode, used in an electronic prototype, developed by the author, is to detect using the technology of measuring chest transimpedance. The ADS1292R integrated circuit was used to measure the impedance, which has a built-in chest movement detection circuit. The method involves the use of a mathematical algorithm for digital signal processing using an SoC system based on an ESP32 controller and using of IoT technologies for wireless data transmission.
