Project IoT : Prototype Jemuran Otomatis Teknik Mesin 2022 Universitas Diponegoro

Summary

In this video, Rahmat Ramadhan from the Mechanical Engineering Department demonstrates his IoT project: an automatic clothesline prototype. Using simple components like a rain sensor, ESP MCU, motor driver, and a DC motor, he showcases how the system detects rain and automatically moves the clothesline. The prototype responds by moving the clothesline when rain is detected and returns to its position once the weather is dry. Rahmat emphasizes how affordable and accessible materials can be used to create practical IoT solutions, with hopes to develop this prototype for real-life use to make everyday tasks easier.

Takeaways

• 😀 Introduction of Rahmat Ramadhan, a student from the Mechanical Engineering Department, presenting the IoT-based automatic clothes dryer project.

Q & A

What is the purpose of the automatic clothes drying prototype in the video?

The prototype is designed to automatically adjust the position of a clothes rack based on rain detection, ensuring that clothes are dried when dry and protected when it rains.

What are the key components needed to create this IoT-based automatic clothes drying prototype?

The key components include a rain sensor, ESP MCU, USB cables, jumper wires, a DC motor, motor driver (L298N), an adapter for powering the motor, screws, bolts, and thread for the clothes rack.

How does the rain sensor function in this prototype?

The rain sensor detects the presence of water, signaling the system when it is raining. When it detects rain, it activates the motor to move the clothes rack to protect the clothes, and when it detects dryness, it moves the rack back to the drying position.

What role does the ESP MCU play in the project?

The ESP MCU controls the operation of the entire system, processing signals from the rain sensor and driving the motor to adjust the clothes rack's position based on the environmental conditions.

How does the motor driver (L298N) contribute to the prototype?

The motor driver controls the speed and direction of the DC motor, allowing the clothes rack to move either left or right depending on the sensor's input (rain or dry conditions).

What happens when the rain sensor detects rain?

When the rain sensor detects water (rain), it triggers the system to move the clothes rack to a protected position, shielding the clothes from the rain.

What is the significance of the 13-second delay in the system's behavior?

The 13-second delay ensures that the clothes rack remains in position long enough for the rain sensor to register a change in environmental conditions (i.e., rain or no rain), before the system makes adjustments.

How is the motion of the clothes rack controlled?

The motion is controlled by the motor, which is powered and directed by the motor driver (L298N), with adjustments made based on inputs from the rain sensor and the ESP MCU.

What happens if the rain sensor no longer detects water?

If the rain sensor detects no water (dry condition), the system automatically moves the clothes rack back to its original drying position, ensuring the clothes are exposed to air for drying.

What is the potential real-world application of this prototype?

The prototype could be developed into a functional product that automatically adjusts clothes racks to optimize drying conditions, making it useful in daily life by protecting clothes from rain and ensuring efficient drying when weather conditions are favorable.
