Ultrasonic Module Distance Measuring Sensor HC-SR04

Description:

Get object/distance detection in your project using the low-cost HC-SR04 Ultrasonic Distance Module from Elegoo. Using the same principle as bats (Echo location), this module uses Trigger and Echo pin to send a signal and listen for it to be ‘bounced back’. With a few lines of code you’ll be detecting objects for your project. This module is the perfect option for detecting objects between 2cm-500cm in front of your project.

• Range – This module can detect objects between 2cm and 500cm in front of itself with an angle of 15 degrees either side.
• Accuracy – The readings of the module can be broken down into 0.3cm increments, which is plenty for most robotics projects
• Mounting – Used by many makers, in many projects, the 4 holes on the circuit board make for easy mounting into your project
• Software – As a favorite distance sensor, there are plenty of libraries and examples available to use with Arduino, Micro:bit, Raspberry Pi and other maker platforms.
• Distance calculation – Once it’s wired up, you’ll use the formula: distance = (traveltime/2) x speed of sound for a measurement in centimeters
