Abstract: This paper provides details about the design and operation of a Collision Avoidance System in smart cars, with the Arduino board as the central control unit, interfaced with an ultrasonic ...

A new technology has been developed that enables cuffless non-invasive blood pressure monitoring by using ultrasonic to track real-time changes in vascular diameter—without the need for a traditional ...

The ultrasonic beam from this sensor penetrates the skin, detects signals reflected from the vessel walls, and measures changes in vessel diameter. Using this principle, it measures the real-time ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

I built a mini radar system using Arduino UNO, HC-SR04 Ultrasonic Sensor, and SG90 Servo Motor, paired with a JavaScript-based visualization dashboard 🖥️. The servo sweeps from 0° to 180°, collecting ...

This is an Internet of Things project created using Raspberry Pi to monitor the water level in a water tank and update a Web GUI or dashboard which can be monitored ...

Sonair’s 3D ultrasonic sensor uses acoustic detection and ranging (ADAR) to enable 360° obstacle detection up to 5 meters. Each ADAR sensor offers a 180×180° field of view, allowing autonomous mobile ...

Hyundai released a position statement this month on repairing front and rear bumpers with corner radar units or ultrasonic sensors. Front and rear bumpers may have corner radar units mounted behind ...
