A dual-SIM setup lets you use one phone to make and receive calls and texts from two numbers. It's also super convenient and can save you serious cash when traveling. We show you how to use two ...

This project utilizes an Arduino Nano along with an ultrasonic sensor to create a distance-based LED color changer. The objective is to demonstrate how the color of LEDs changes based on the proxim ...

The demo kit includes a TDK demo board with USB-A to Micro-B cable, two ultrasonic sensor modules, two sensor cables and two seals. Its software package allows the user to monitor the sensor in many ...

This article deals with topic of creating an ultrasonic immersion sensor for a PIKA-19 field measurement probe, and the possibility of encoding and transmitting control commands and data from the ...

Wind direction can be calculated by taking velocity readings from two ultrasonic sensor pairs perpendicular to each other and using a bit of simple trigonometry.

An Arduino compatible board (e.g. Arduino UNO): Arduino UNO / Arduino Mega A HC-SR04 ultrasonic sensor / A Ping))) ultrasonic sensor: HC-SR04 (Optional - For aqqurate distance values) A DHT ...

The oscillation frequency of the ultrasonic scaler was 30 kHz, and the output power and flow rate of the cooling water were variable. Velocity field measurements using PIV were performed to clarify ...

Ultrasonic sensors can detect objects placed within their range, but they cannot distinguish between different shapes and sizes. However, one can overcome this limitation can by using two sensors ...

Qualcomm’s second-generation ultrasonic fingerprint reader — the 3D Sonic Max —is 17 times larger than the original, in an attempt to solve the first-gen model’s issues.
