What is the main purpose of the HC-SR04 sensor?
The HC-SR04 Ultrasonic Distance Sensor is a sensor used for detecting the distance to an object using sonar. It’s ideal for any robotics projects your have which require you to avoid objects, by detecting how close they are you can steer away from them!
What is the use of trigger pin in ultrasonic sensor?
Trig (Trigger) pin is used to trigger the ultrasonic sound pulses. Echo pin produces a pulse when the reflected signal is received. The length of the pulse is proportional to the time it took for the transmitted signal to be detected.
What can the hc-sr04 distance sensor be used for?
The HC-SR04 is an inexpensive Ultrasonic Distance Sensor that can assist your robot in navigating around a room. With a bit of care and an additional component it can also be used as a measurement device.
What kind of power supply does a hc-sr04 have?
The HC-SR04 has the following four connections: VCC – This is the 5 Volt positive power supply. Trig – This is the “Trigger” pin, the one driven to send the ultrasonic pulses. Echo – This is the pin that produces a pulse when the reflected signal is received.
What can I use the distance sensor for?
For example, you can use the distance information to avoid obstacles that might be in your way. You can also use the HC-SR04 distance sensor to detect when the distance to an object has radically changed. You can use something like MyDevices Cayenne or your own custom solution to alert you to the change.
Where do I upload code for Arduino distance sensor?
If you’re having trouble uploading the code to the Arduino then double check that you have selected it in the IDE. This is located under “ Tools->Port: ” and “ Tools->Board ” . I hope that this tutorial has shown you all the steps on how to setup a Arduino distance sensor that makes use of the HC-SR04.
