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 ...

This sketch is an example of 2 units of HC-SR04 Ranging Module connected to Arduino Uno ATMega 238. The dual HC-SR04 trigger by the same output pin 2 and echo at pin 3 (PCINT19) and 4 (PCINT20). It ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield.

He wanted to use the less expensive HC-SR04 ultrasonic rangefinder in a prototype. Longer term he wanted to have the choice of either a Parallax PING or MaxBotix ultrasonic sensor for their better ...

Specifications of the ultrasonic sonar distance sensor that can be used with Arduino, Raspberry Pi, CircuitPython and more include : – Power & Logic Voltage: DC 5V – Current during measurment ...

Our kit includes the Maker Uno RP2040 itself, four Grove to jumper cables, a USB-A to USB-C cable, a soil moisture sensor with one Grove cable, an HC-SR04 ultrasonic sensor with a Grove cable, a SG90 ...

This research aims to develop a RADAR system using an ultrasonic sensor (HC-SR04), servo motor (SG90), and Arduino UNO. This RADAR system can detect objects in the vicinity and display information ...
