Fitness-freak persons are increasing in day by day in the modern lifestyle and therefore can be considered an essential part while making the present proposal. The embedded fitness tracker does the same. Google Fit is a free-to-use application developed by Google for multiple devices like mobile phones based on Android and IOS. It also has extended its support to multiple wearable operating system and devices like iWatch, MI watch, Fitbit, and other smart watches. Data of one’s daily activity are stored through these devices and are synced to the cloud via internet. Here, the user can sync his/her account of Google Fit to the mirror by replicating the data from Google Fit server to our Cloud Console and then viewing the data on owns Mirror. Block diagram is given in Figure 4.6.

      News updates are fetched within the mirror directly from Times of India world news with 1 hour interval. The present proposal deals with one extremely essential feature which is given at free of cost; that is weather predictions with utmost accuracy. This is helpful for making daily routine for people with whatever professions. Phone notifications are fetched into the mirror and stayed tuned.

      4.9 Results

      The total result section in this manuscript is subdivided into three parts: circuit design, LDR data display, and API data from the informative interface. In the circuit design section, we have discussed about PIR sensor and its connections, LDR, control unit design, and Rasberry Pi configuration. In the display section, we have shown the variation of data in LDR, and API data using Google Cloud Console is exhibited in the last phase of this section.

      4.9.1 Circuit Design

      We have started with the setting up of Raspberry Pi 3 Model B+, which operates at 1.4GHz. This is supported by Bluetooth 4.2.1, along with wireless ac Wi-Fi. The process begins with connecting the microphone and speaker to the Raspberry Pi and then by inserting the SD card into it. Thereafter, USB keyboard, mouse, and HDMI monitor are added sequentially.

At last, Ethernet cable is connected to Wi-Fi network. After successful configuration, date and time will be set.

The next important hardware part is the Pyroelectric Infrared (PIR) Sensor Module, required for human body detection. Its implementation into the interface circuit is shown in Figure 4.7.

In the next phase, control unit is designed. Microcontroller is connected with relay module and LDR, where proper power supply is required. Block diagram is given in Figure 4.8.

      4.9.2 LDR Data

After finalizing the circuit, LDR gives data as output which is a series of pulses. Plots are shown in Figure 4.8. The first two plots of Figure 4.9 show the variation of pulses in LDR where the third diagram shows the reading across the device.

      4.9.3 API Data

At first, we analyze the results obtained from Google Cloud Console and provided them sequentially (Figures 4.10, 4.11, 4.12, and 4.13) below. Figure 4.10 exhibits the operational workbook with API keys, whereas in Figure 4.11, corresponding graphs are provided in different days, as obtained from cloud console. Traffic variations, corresponding error, and median latency for the same days are provided in that plot.

Figure 4.13 API data push and pull traffic data graph.

For different APIs, call log is extremely important in order to note down the busy schedule. Therefore, important APIs like Google Assistance, JavaScript, Directions, YouTube, and custom search are noted. This is shown in Figure 4.12. In this case, it is also
