An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor, and ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino. Trump overpowers Musk's ...

The research team developed the sensor using an organic semiconductor known as DPP-DTT. They began by patterning interdigitated platinum electrodes onto a substrate using lithography. The DPP-DTT ...

Images, and the devices that capture them, are my focus. I've covered cameras at PCMag for the past 13 years, which has given me a front row seat for the DSLR to mirrorless transition, the ...

Radar System Using ESP8266, Ultrasonic Sensor (HC-SR04), Servo Motor (SG90), and Blynk Control This project demonstrates a real-time Radar System built using the ESP8266 NodeMCU, HC-SR04 ultrasonic ...

Abstract: We present a low-power gas sensor design based on a capacitive micromachined ultrasonic transducer (CMUT), for use on self-powered wearable platforms. Earlier a CMUT-based sensor, with 70-mW ...

We propose a micro-ultrasonic diagnosis using an all-optical ultrasound-based spectral sensing (AOUSS) technique for sensitive and quantitative characterization of early stage and whole blood ...

The aim of this mission is to clean and cover all the rural and urban areas of the country so that to present this country as an ideal country before the world with the proliferation of Internet of ...
