Ultrasonic sensor arduino project.
Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm.
In circuit connections ultrasonic sensor module s trigger and echo pins are directly connected to pin 18 a4 and 19 a5 of arduino.
Connect the vcc and gnd.
In one of our previous arduino project we used the sensor hc sr04 to allow a robot to see obstacles while moving and to act accordingly the hc sr04 is a very popular ultrasonic sensor and you should definitely learn how to make use of it.
What is an ultrasonic sensor.
Connect the positive terminal with pin 8 of arduino and negative terminal to gnd.
It offers excellent non contact range detection with high accuracy and stable readings in an easy to use package from 2 cm to 400 cm or 1 to 13 feet.
It emits an ultrasound at 40 000 hz 40khz which travels through the air and if there is an object or obstacle on its path it will bounce back to the module.
It allows to detect a presence or to measure a distance via ultrasounds.
The hc sr04 ultrasonic sensor uses sonar to determine the distance of an object just like the bats do.
Simple project with the ultrasonic sensor hc sr04 led arduino tutoriel.
Ultrasonic rangefinder with processing.
Obstacle distance is measured using ultrasonic sensor and arduino.
The data is processed using processing and the distance is marked.
