So, we have covered pretty much everything that we need to know about using the HC-SR04 Ultrasonic sensor with Arduino. It’s a great sensor for many DIY electronics projects where we need a non-contact distance measuring, detection of presence or objects, level or position something etc. I...
Here’s the pinout of the HC-SR04 Ultrasonic Sensor.VCC Powers the sensor (5V) Trig Trigger Input Pin Echo Echo Output Pin GND Common GNDHow Does the HC-SR04 Ultrasonic Sensor Work?The ultrasonic sensor uses sonar to determine the distance to an object. Here’s how it works:...
Ultrasonic sensor HC-SR04 is used to measure the distance to an object by using ultrasonic waves.PinoutThe ultrasonic sensor HC-SR04 includes four pins:VCC pin: needs to be connected to VCC (5V) GND pin: needs to be connected to GND (0V) TRIG pin: this pin receives the control signal...
The HC-SR04 is an inexpensive, easy to use ultrasonic distance sensor, with a range of 2cm to 400 cm. It is commonly used in obstacle avoiding robots and automation projects. In this tutorial, you will learn how the sensor works and how to use it with Arduino....
