“…As the user begins using their device, the system will automatically start the process of being initialized. The ultrasonic sensor will detect how much distance between the user and the device they are using [24], [25]. The distance data that has been read by the ultrasonic sensor will be sent to Blynk to be stored.…”

Gadgets have certainly become an integral part of our daily lives. From smartphones and tablets to laptops and smartwatches, we rely on these devices to stay connected, entertained, and productive throughout the day. Excessive usage of gadgets for a long time and unhealthy habits will lead to health problems such as myopia. Using gadgets at a close distance is one of the most common unhealthy habits among gadget users, especially children. This study, called "smart distance alert system" is developed to address the unhealthy habit of using gadgets at a close distance. The developed prototype operates by measuring the distance between the user and the gadget screen using an ultrasonic sensor. The buzzer and vibration motor work as an alert system, activating when the distance is less than 50 cm. Parents or guardians will get notifications through the Blynk application. The entire prototype is controlled by NodeMicrocontroller unit.

“…Figure 3 demonstrates the circuit design and the connection of the pins for each built-in component. The components in the figure are ultrasonic sensors [19], [20], Arduino Nano [21], [22] , Bluetooth module [23], MPU-6050 3-axis gyroscope and accelerometer [24], [25] as a position sensor, microSd card module, and battery. All of the power voltage common collector (VCC) and ground pins of the ultrasonic sensors are connected to +5 volt and ground pin on the Arduino.…”

This effort develops and uses a smart stick to help blind individuals walk more safely and avoid hazards. This research paper involved to develop smart stick for blind people to help them to walk safely by avoiding obstructions, and at emergency conditions sent their location to person in charge like a doctor or relatives to help them accordingly. Three ultrasonic sensors are used in the proposed device's architecture to detect obstructions at three different heights, low, mid, and high obstructions using speaker to alert the blind person. An emergency message with the location of the blind person's phone is sent through a mobile app to the doctor or person in charge whenever the designed smart stick's emergency button is touched, or the stick is dropped down. The Arduino Uno platform, Bluetooth model, MPU-6050 3-axis gyroscope as a position sensor, and microSd card module has been used to effectively implement the stick. At the testing stage, the device gave good results. The user received notifications in the form of voice messages and vibrations from the smart stick when it detects things or obstacles in front of them. Additionally, even though they cannot directly activate it, the automated emergency condition has been detection and activated.
