Design Of Water Level Measuring Devices Using HC-SR04 Sensors Based On ATmega8535 Microcontroller
Introduction
Water is a vital resource for human life, and its availability is crucial for various activities. Water reservoirs play a significant role in ensuring a stable water supply. However, monitoring the water level in these reservoirs is still widely done manually, which can be challenging, especially when the reservoir is located in a difficult-to-reach area. To overcome these problems, a more practical and efficient solution is needed, namely the design of automatic water level measuring devices.
The Need for Automatic Water Level Measurement
Manual water level measurement is a simple and cost-effective method, but it has several limitations. For instance, it requires frequent visits to the reservoir, which can be time-consuming and labor-intensive. Moreover, it can be challenging to measure the water level accurately, especially in reservoirs with complex geometries. Automatic water level measurement devices can help overcome these limitations by providing real-time information on water levels, allowing users to control water availability with ease.
Automatic Measurement System Based on Microcontroller
One of the technologies that can be applied in the design of automatic water level measuring devices is the use of HC-SR04 ultrasonic sensors and ATmega8535 microcontroller. The HC-SR04 sensor works on the principle of emission and reception of ultrasonic waves to measure the distance between the sensor and the water level. The distance data obtained is then processed by the ATmega8535 microcontroller to display water level information on a digital display.
HC-SR04 Ultrasonic Sensor
The HC-SR04 ultrasonic sensor is a popular choice for distance measurement applications due to its high accuracy and ease of use. It works by emitting an ultrasonic wave and measuring the time it takes for the wave to bounce back from the target object. In this case, the target object is the water level in the reservoir. The sensor can measure distances up to 4 meters with an accuracy of ±3 mm.
ATmega8535 Microcontroller
The ATmega8535 microcontroller is a popular choice for microcontroller-based projects due to its high performance and low power consumption. It has a 8-bit RISC architecture and can operate at frequencies up to 16 MHz. The microcontroller has a range of peripherals, including timers, counters, and serial communication interfaces, which make it suitable for a wide range of applications.
