In this tutorial, you will learn how to send WhatsApp messages directly from an Arduino UNO R4 WiFi using the CircuitDigest Cloud Whastapp API. Instead of using a GSM module, SIM card, or complex ...

A small PlatformIO/Arduino project that measures distance using an ultrasonic sensor (HC-SR04 or similar) and prints the measured distance over the serial port. This README explains how to open the ...

int max_ultrasonic_distance_cm = 400; // set the maximum measureable distance for the ultrasonic sensor to 400cm NewPing sonar(ULTRASONIC_TRIGGER, ULTRASONIC_ECHO ...

In this video, I'm testing out the VL53L0x Time Of Flight sensor that optically measures distance with some IR laser to see if it will be a good option to use in future versions of my pellet level ...

The Korea Research Institute of Standards and Science (KRISS) has developed an ultrasonic sensor technology that applies a ...

Ultrasonics refers to signals that are above the human hearing span (>20 kHz), and usually in the 40- to 70-kHz range. These signals are used like radar—they’re radiated toward a target and reflected ...

Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...

A quantum net for dark matter: A distributed intercity network of quantum sensors is placing additional constraints on the parameters that axionic dark matter could have. (Courtesy: USTC) A new of way ...

Abstract: An advanced blind assistance device integrates an ultrasonic sensor, Arduino UNO board, buzzer, and GSM module to create a cost-effective solution for enhancing the safety and autonomy of ...

Abstract: A long-distance, strong-misalignment tolerance seawater capacitive power transfer system with two insulated electric-field couplers and single-wire for underwater sensors is proposed in this ...
