Design Of Hand Dryer And Temperature Using Internet -based Ultrasonic Sensors
Introduction
In recent years, the importance of maintaining hand hygiene and monitoring body temperature has become a top priority in public places such as hospitals, schools, and shopping centers. To address this need, this study aimed to design a hand dryer and IoT-based temperature gauge using ultrasonic sensors. The tool was developed using an HC-SR04 ultrasonic sensor and MLX90614 temperature sensor, which were connected to a Nodemcu ESP8266 microcontroller. This microcontroller is one of the popular platforms in the development of the Internet of Things (IoT). The tool was also equipped with jumper cables, adapters, transistors, and Blynk applications that function as the display interface for measurement results.
Purpose and Benefits of Tools
The primary purpose of making this tool is to dry hands and measure body temperature automatically, saving time in its use. By utilizing IoT technology, this tool provides convenience for users, especially in public places where cleanliness and health are top priorities. The tool's ability to perform two functions at once - drying hands and measuring temperature - makes it a valuable asset in maintaining hand hygiene and monitoring body temperature.
Testing Methodology
The testing method used in this study was a quantitative data collection method, which was carried out on five different samples. The test results showed that this tool has a good level of accuracy with an average error of 2.26% when compared to standard measurement instruments. This indicates that the tool is quite reliable and can be used in everyday situations.
How Tools Work
The use of this tool is very easy. To dry the hand, the user simply puts the hand on the HC-SR04 sensor. The sensor will detect the presence of the hand and automatically turn on the fan to dry the hand. Meanwhile, to measure body temperature, users only need to put the object in front of the MLX90614 sensor. This sensor will immediately take measurements of the temperature of the object and display the results through the Blynk application.
Analysis and Strengths
One of the advantages of this tool is its ability to perform two functions at once - drying hands and measuring temperature. This is very relevant in the current era, where the health protocol is very important. With this tool, users can not only maintain hand hygiene but also monitor body temperature, which can be an initial indicator of health problems.
In addition, the application of IoT technology allows this tool to connect with other devices, provide data in real-time, and allow users to monitor measurement results from a distance. Thus, this tool does not only function as a sanitation tool, but also as a sophisticated health monitoring tool.
Limitations and Future Work
While this tool has shown promising results, there are some limitations that need to be addressed. For example, the tool's accuracy may be affected by external factors such as temperature and humidity. Additionally, the tool's battery life may be limited, requiring users to recharge or replace the battery frequently.
Future work can focus on improving the tool's accuracy and battery life. Additionally, the tool can be further developed to include additional features such as alert systems for abnormal temperature readings or integration with other health monitoring devices.
Conclusion
Making a hand dryer and IoT-based temperature gauge using an ultrasonic sensor is an innovation that is not only efficient but also very useful in the context of public health. With a good level of accuracy and ease of use, this tool is expected to make a positive contribution in efforts to maintain health and cleanliness, especially in public places. Innovations like this are a step forward in the use of technology to support daily needs, especially in the post-Pandemic era.
