Introduction

In the world of technology, one of the most interesting applications is the use of ultrasonic sensors in distance measurements. These sensors have been widely used in various fields, including industrial automation, robotics, and security systems. In this article, we will discuss the SR04 ultrasonic sensor and its recipient application, which is designed to detect close, far, and quite far away objects. This system uses the ATmega 8535 microcontroller and SR04 type ultrasonic sensor as the main input to determine the distance from the detected object.

SR04 Ultrasonic Sensor Working Principle

The SR04 ultrasonic sensor consists of two main parts: transmitters and ultrasonic wave receivers. The distance measurement process starts when the transmitter circuit emits ultrasonic waves for 200 microseconds. This wave then moves through the air with a speed of about 344 meters per second. When the waves hit the object, the waves will be reflected back to the recipient on the sensor. By knowing the time needed for the waves to go and return, we can calculate the distance of the object.

The SR04 ultrasonic sensor uses a simple yet effective principle to measure distance. The transmitter sends out a high-frequency sound wave, which is beyond the range of human hearing. This wave travels through the air and hits the object, and then bounces back to the sensor. The sensor then measures the time it takes for the wave to return, and uses this information to calculate the distance of the object. This process is repeated continuously, allowing the sensor to provide accurate and real-time distance measurements.

The Use of ATMEGA 8535 Microcontroller

This system utilizes the Microcontroller of the ATmega 8535, which has a frequency of up to 8 MHz and the capability of 8-bit. In distance measurements, the method used is to use the timer/counter that is already in the microcontroller. This timer allows the system to calculate the time required for ultrasonic waves to reach the object and return to the sensor. The results of this calculation are then converted to distance.

The ATmega 8535 microcontroller is a powerful and versatile device that is widely used in various applications. Its high frequency and 8-bit capability make it an ideal choice for distance measurement applications. The microcontroller's timer/counter feature allows it to accurately measure the time it takes for the ultrasonic wave to return, and convert this information into a distance measurement.

Programming the SR04 Ultrasonic Sensor

The program used to operate this system is written using the C programming language. One of the software that is often used for this is the Vision AVR code, which is designed to produce an efficient code both in terms of size and speed of execution. The advantage of Code Vision AVR is that it can optimize the program to minimize the use of resources, so that the microcontroller can function optimally.

The C programming language is a popular choice for programming microcontrollers, due to its simplicity and flexibility. The Vision AVR code is a powerful tool that allows programmers to create efficient and optimized code for the ATmega 8535 microcontroller. By using this code, programmers can create complex programs that can accurately measure distance and perform other tasks.
