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 ...
This project is a simple automatic toll gate system built using Arduino, an ultrasonic sensor, a servo motor, and a 16x2 LCD display. The system detects when a vehicle approaches the gate, opens the ...

Accurate distance measuring with VL53L0X time of flight sensor in ESPHome
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 ...
This project demonstrates how to interface an HC-SR04 ultrasonic distance sensor with an SSD1306 OLED display using the STM32 Blue Pill microcontroller. The system measures distances and displays them ...
Modeling and Implementation of a Long-Distance Seawater Single-Wire CPT System for Underwater Sensor
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 ...
Abstract: Ultrasonic waveguide techniques are most familiar to monitor temperatures in the hostile environments. A single waveguide could be used as multiple sensors. In the present work, a thin strip ...
