Progress on Blind Spot Monitoring System project for my Royal Enfield

The module has a single LED that turns green or blue to indicate left or right-side overtaking, respectively. This setup is intended for initial data analysis.

BHPian pragyaal recently shared this with other enthusiasts:

Continuation from my earlier part:

The prototype for phase 2 is now ready to be installed. There are many more components now. I built one part which is now based on the ESP32 module with JSN-SR04T version 3.0 sensors. This acts as a transmitter unit and another with ESP32 acts as a receiver which I will mount near handle bar, this avoids any unnecessary wiring.

Above is the ESP32 module with two ultrasonic sensors. I tested numerous SR04T ultrasonic sensors and, after extensive comparison and research, found that the JSN-SR04T version 3.0 provides the most precise and consistent readings.

The plan for the future is to put small LED on mirrors but routing the internal cable through handle bar is something I still am unable to figure out

For now, I will place another ESP32 module on the handlebar. This module has a single LED that turns green or blue to indicate left or right-side overtaking, respectively. This setup is intended for initial data analysis.

This front module also includes two buttons, which I will mount on the left side of the handlebar—one green and one red. The plan is to test the readings by pressing the green button if the LED indication is correct, or the red button if the reading is invalid.

Here is the button.

For logging data, I experimented with various methods like using an SD card and Google Sheets. However, for now, I will keep my cellphone in the bag, and the plan is for the front ESP32 to log data directly to the cellphone.

After conducting some data analysis, I plan to modify the code with one of the following options:

• Use the Bluetooth feature of the ESP32 to provide an audio or voice alert via my helmet Bluetooth system.
• Fix small LEDs on the mirrors. (This is bit tricky as I have not figured out a way to route wiring in the handle bar to my bar end mirrors)

The data analysis and software adjustments might take a few days or weeks. I will update you soon on the software component and share insights from the data analysis.
