Apparatus
Apparatus refers to the components that are needed for the project. The components required for designing a sensor using Arduino include.
- One Breadboard
- Arduino Uno R3 (Generally this model is only preferred_
- One Ultrasonic Sensor (HC-SR04)
- Some wires for making connections.
These devices are easily available at nearby electronics shops.
Arduino – Ultrasonic Sensor
Sensors are widely used for detecting devices by approximating their distance from the source. One such example of a sensor is the HC-SR04 ultrasonic sensor which uses the SONAR technique for the sensing purpose. The main feature of this sensor is to mimic the nature of bats and therefore predict the distance of objects without actually establishing contact with the device.
In this article, we will study how to design this ultrasonic sensor using the Arduino board and programming software. We will study the specifications needed for this sensor, and the methods and circuit diagrams used for designing this sensor. In addition to this, we will see the Arduino code written on IDE that will result in a sensor.
