Develop a UML state machine that describes the behaviour of the ECG sensor. Be as detailed as possible and make any assumptions necessary, as long as you do not over-simplify the system to create your model.

ECG Sensor The ECG Sensor is composed of two components: a microcontroller running software and an electronic circuit connected to electrodes to measure the physiological signal. This section describes the behavior of the software executing on the microcontroller. The ECG Sensor operates in two modes: Heart Rate Monitoring (HRM) mode Full ECG Monitoring (FEM) mode 1. 2. To understand the difference between these two modes, it is necessary to introduce a typical ECG record (shown in Figure 2). An ECG record contains several electrical components, but the most prominent one is called the R peak (which coincides with the depolarization of the ventricles). The most accurate way to estimate the heart rate of a human is to count the number of R peaks occurring in a minute When the sensor is in the HRM mode, it simply counts the number of R peaks occurring in the ECG record every minute and sends a signal carrying the total of the count to the Health Monitor application. When the sensor is in the FEM mode, it collects the entire ECG record (as opposed to counting R peaks) It will send a signal carrying the collected record every 10 seconds to the Health Monitor application.
