9/21/2023 0 Comments Ultrasonic sensor arduino circuitIn this project two circuits are used: a transmitter circuit and a receiver circuit. This project is wireless so, it is easy to install and it can work up to 100 meters. Thus, the Arduino water level indicator helps in preventing wastage of water in overhead tank. This project can be further enhanced to control the water level in the tank by turning it ON, when the water level is LOW, and turning it OFF when the water level is HIGH. The objective of this project is to notify the user the amount of water that is present in the overhead water tank. So download from below.Wireless Water Level Indicator Using Ultrasonic sensor & Arduino is an amazing and very useful project. But before that, you need to add these libraries. Circuit: Interfacing Ultrasonic Sensor with Arduino & OLEDįor project Range Finder Using Ultrasonic Sensor & Arduino with OLED Display, copy this code then compile and upload to your Arduino board. OLED possesses high application potential for virtually all types of displays and is regarded as the ultimate technology for the next generation of flat-panel displays. In contrast to LCD technology, OLED does not require a backlight. ( Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. The package includes display board, display,4 pin male header pre-soldered to board. The display module can be interfaced with any microcontroller using SPI/IIC protocols. This is a 0.96 inch blue OLED display module. The ultrasonic sensor is measuring the time it takes to hit the object and then come back but we need only time that it takes to hit the object. S = v * tThe ultrasonic wave is basically a sound wave that travels at a speed of 340 m/s (0.034 cm/s). We will use the following equation to calculate the distance. We will have to convert this time into cm to calculate the distance traveled. If they strike an object, then they are reflected back as echo signals to the sensor, which itself computes the distance to the target based on the time-span between emitting the signal and receiving the echo. These propagate in the air at the velocity of sound. Ultrasonic sensors emit short, high-frequency sound pulses at regular intervals. Maximum measuring range: 400 cm or 4 meter.The specifications of the ultrasonic distance sensor HC-SR04 are below: A waterproof version of this Ultrasonic Sensor is also available called as JSN-SR04T/AJ-SR04M. It comes complete with the ultrasonic transmitter and a receiver module. Its operation is not affected by sunlight or black material like sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package.įrom 2cm to 400 cm or 1” to 13 feet. The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object like bats do. So let’s learn about Distance Measurement Using Arduino & HC-SR04 Ultrasonic Sensor.Ĭheck the previous project: Distance Measurement Using Arduino & HC-SR04 Ultrasonic Sensor Components Required: It sends an ultrasonic wave of a certain frequency that comes back after hitting the object and calculates the time traveled by it. The ultrasonic sensor is used to measure the distance. In this project, we are going to make Arduino Ultrasonic Sensor Range Finder with HC-SR04 on OLED Display. ![]()
