TDK showcases its suite of sensing solutions, including MEMS IMUs, MEMS microphones, and ultrasonic ToF sensors at Sensors ...

There’s also support for WiFi 6 and Bluetooth 5.2 LE, and a bunch of additional I/O features including a 5-way joystick, capacitive touch sensor, 4 buttons, a microphone and 2MP camera, plus ...

The SpeakerHub isn’t as loud as the sensor alarm, and silencing it isn’t intuitive. We measured the SpeakerHub’s maximum volume from 6 feet at around 66 decibels, so it’s certainly audible ...

Wi-Fi controlled four-wheeled scout vehicle using dual Arduino Uno R4 boards, ultrasonic sensor, turret rotation, ... Smart Arduino alert system using PIR, ultrasonic, and water sensors with LED and ...

Ultrasonic sensor measurements are mostly based on the determination of the time of flight (TOF). The development of a digital algorithm for pulse-echo measurement applications, based on the use of a ...

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 power ...

Water level monitor using open-source microcontrollers (Arduino, ESP8266, ESP32) and ultrasonic sensors HC-SR04 / JSN-SR04T and similar with Trigger and Echo signals. Arduino Core & ESP-IDF ...
