This project demonstrates how to use an HC-SR04 ultrasonic sensor with Arduino and ESP32 to measure distances accurately and integrate them into DIY electronics or IoT projects. The ultrasonic sensor ...

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 ...

This project is a smart water level controller built using Arduino UNO, an ultrasonic sensor, and EEPROM for memory storage. The system automatically monitors the water level in a tank and controls ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

This post is a review of the popular waterproof ultrasonic sensor JSN-SR04T. I hope this will serve as a backdrop for some interesting ultrasonic distance sensor experiments and projects. A number of ...

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting ...

Abstract: This is the time of pandemic COVID-19. There is a need of social distancing. Thus, it is a better way to have automatic systems. One of the important medical symptoms being detected is fever ...
