Abstract: Accurately measuring transformer ... sensor arrays. The probe contains 16 sensors, which are divided into four arrays. The sensors are bare die chips diced from an 8-in wafer and then wire ...

Installing a smart water sensor can save you a lot of money and hassle. The best models we've tested immediately alert you to leaks and even shut off your home's water supply. I’ve been working ...

Walking safely and confidently can be a challenging task for visually impaired individuals, but with the help of technology, we can make it easier for them. This DIY Blind Stick is an innovative yet ...

Enables autonomous driving of a 2 or 4 wheel car with an Arduino and a Adafruit Motor Shield V2. To avoid obstacles a HC-SR04 Ultrasonic sensor mounted on a SG90 Servo continuously scans the area.

Conventional waterproof sensors mainly ... We propose an electromyogram sensor system that uses a flexible wearable band to prevent water from entering between the electrode and the skin and stably ...

Not so, if you use a pair of specialised ultrasonic transducer arrays to move the air instead! (Video, embedded below) Three banks of thrusters provide a 180 degree steerable net force Details are ...

HAL-based driver for the HC-SR04 ultrasonic sensor, implemented on an STM32F446RE Nucleo board. Key features include temperature-compensated distance calculation, pulse width validation with hardware ...

and you’re having trouble measuring the whole six feet apart from other people deal by eye, then [Guido Bonelli] has a solution for you. With a standard old HC-SR04 ultrasonic sensor ...
