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

While only two of the Grove connectors support analog, any of the 6 Grove connectors and the Maker port can be configured to take a digital sensor. In this review, we will be using an HC-SR04 ...

An ultrasonic sensor is positioned outside the box to detect the presence of a hand within a four-inch range. Upon sensing an obstacle, ... the Arduino code is equally basic, too.

Amazon Echo’s built-in ultrasonic motion sensing can let you easily automate lights and fans with Alexa routines, without buying anything else.

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Arduino Uno is a microcontroller board that is used to perform various tasks in different circuits. It needs a Code in C language to operate. We are using the Arduino Uno board in this project but you ...

code: // C++ code // include the library code: #include // initialize the library with the numbers of the interface pins LiquidCrystal lcd(12, 11, 5, 4, 3, 2); int ultrasonic = 0; long ...

Arduino UNO circuit board [8] and an HC-SR04 ultrasonic distance sensor [9] were used for data collection and are shown in Figure 2. Arduino UNO was placed on upper face of top plate and ultrasonic ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...
