PIR Sensor Application and Ultrasonic Sensor as a Controller of Automatic Water Faucets Based on ATMEGA 8535

Introduction

Water faucets are an essential part of our daily lives, providing us with access to clean water for drinking, cooking, and hygiene. However, traditional manual water faucets have several drawbacks, including waste of water and the risk of damage to the faucet itself. In an effort to overcome these problems, researchers have developed automatic water faucet systems using Passive Infrared (PIR) and ATmega 8535 sensors. This innovative system is designed to detect user presence, ensuring that water only flows when needed.

Background

Traditional manual water faucets require users to rotate or move the faucet up or down to drain water. However, this system has several weaknesses, including waste of water and the risk of damage to the faucet itself. In addition, manual faucets can be inconvenient, especially for people with disabilities or mobility issues. The development of automatic water faucet systems using PIR and ATmega 8535 sensors aims to address these issues and provide a more efficient and convenient solution for water usage.

PIR Sensor Application

The PIR sensor is a type of object detector that uses infrared radiation to detect the presence of objects. In the context of automatic water faucets, the PIR sensor is used to detect the presence of a human body. When a user approaches the faucet, the PIR sensor sends a signal to the Arduino control center, which then sends instructions to the relay to activate the switch connected to the solenoid valve. The solenoid valve functions as a water flow valve, allowing water to flow only when needed.

Ultrasonic Sensor Application

In addition to the PIR sensor, the ultrasonic sensor is also used in the automatic water faucet system. The ultrasonic sensor uses high-frequency sound waves to measure the distance between the sensor and an object. In this case, the ultrasonic sensor is used to detect the presence of a user and measure the distance between the user and the faucet. The sensor sends a signal to the Arduino control center, which then sends instructions to the relay to activate the switch connected to the solenoid valve.

ATMEGA 8535 Microcontroller

The ATMEGA 8535 microcontroller is a type of microcontroller that is used in the automatic water faucet system. The microcontroller is responsible for receiving signals from the PIR and ultrasonic sensors and sending instructions to the relay to activate the switch connected to the solenoid valve. The ATMEGA 8535 microcontroller is a powerful and versatile device that can be programmed to perform a wide range of tasks.

System Design

The automatic water faucet system consists of several components, including the PIR and ultrasonic sensors, the ATMEGA 8535 microcontroller, the relay, and the solenoid valve. The system is designed to detect user presence and measure the distance between the user and the faucet. When a user approaches the faucet, the PIR and ultrasonic sensors send signals to the Arduino control center, which then sends instructions to the relay to activate the switch connected to the solenoid valve. The solenoid valve functions as a water flow valve, allowing water to flow only when needed.

Results

The results of this study indicate that the PIR sensor is able to detect objects within a maximum distance of 15 cm. In addition, the ratio between the use of manual faucets and automatic faucets shows a savings of 20% in water use when using an automatic system. However, there are important notes regarding the performance of PIR sensors that have a fairly low sensitivity. This sensor needs to be parallel to the object detected so that it can function properly. If the object is not appropriate, the sensor cannot work optimally.

Conclusion

The automatic water faucet system using PIR and ATmega 8535 sensors is a innovative solution for reducing water waste and providing a more efficient and convenient solution for water usage. The system is designed to detect user presence and measure the distance between the user and the faucet. The results of this study indicate that the PIR sensor is able to detect objects within a maximum distance of 15 cm and that the ratio between the use of manual faucets and automatic faucets shows a savings of 20% in water use when using an automatic system. However, there are important notes regarding the performance of PIR sensors that have a fairly low sensitivity.

Future research is advised to consider the use of more quality and sensitive sensors. It is intended that the ablution faucet system can automatically function more efficiently and provide greater benefits, both in terms of water savings and operational reliability. In addition, future research can focus on improving the performance of PIR sensors and developing more efficient and convenient solutions for water usage.
