The AutoSense Bed project was developed with the vision of using technology to improve healthcare and caregiving. In many Vietnamese families, especially those with elderly or sick members living alone, providing constant care can be challenging. The team set out to create an automated system that monitors health conditions, reduces caregiver workload, and ensures patients receive timely attention—particularly when professional healthcare support is limited.

HOW DOES IT WORK

The AutoSense Bed integrates health monitoring, mobility assistance, and remote control into one comprehensive system. At its core, an ESP32 ESP-WROOM-32 microcontroller collects and processes health data from multiple sensors:

• A GY-MAX30100 sensor continuously measures heart rate and blood oxygen levels
• An arm-style blood pressure monitor records blood pressure and pulse
• A GY-906 MLX90614 infrared temperature sensor measures body temperature without contact, ensuring patient comfort and hygiene

All readings are displayed on a local screen and transmitted via Wi-Fi or Bluetooth to a mobile application, allowing caregivers to monitor the patient’s condition remotely from anywhere.

Additionally, the bed’s mechanical system—powered by a stepper motor and T20 lead screw—enables smooth lifting, lowering, and repositioning of the patient. Caregivers can adjust these settings through the mobile app, ensuring safety and convenience even when they’re not physically present.

IMPACT

The AutoSense Bed combines automation, IoT, and healthcare technology to create a practical solution for real-world needs. It demonstrates how students can apply coding, engineering, and problem-solving skills to address meaningful community challenges—from supporting elderly care to improving home healthcare systems in Vietnam.

In response to declining air quality caused by environmental pollution and climate change—particularly the dry conditions created by air conditioner use—a talented student from Long Tri A Secondary School has developed an innovative automatic mist humidifier. This groundbreaking project maintains optimal humidity levels, reduces temperature, protects health, and conserves energy while addressing the limitations of traditional humidification methods in agriculture, especially within greenhouse environments.

HOW DOES IT WORK

The automatic mist humidifier system combines advanced components to efficiently monitor and regulate environmental conditions through four key processes:

Data Collection
DHT11/DHT22 sensors continuously measure temperature and humidity, transmitting real-time data to the control unit for immediate analysis.

Signal Processing
The central control circuit (Arduino/ESP32) analyzes sensor data and compares it against pre-configured thresholds to determine necessary adjustments.

Automated Adjustment
When humidity drops below the set threshold, the system activates the ultrasonic mist humidifier to increase moisture levels. If temperature exceeds the allowed limit, the TEC-12706 Peltier cooler activates to cool the air. Once desired levels are achieved, the system automatically shuts off to conserve energy and water.

Continuous Operation
This process repeats continuously, ensuring a stable and optimal environment at all times.
The system shows excellent potential for future enhancements, including integration with mobile applications for remote monitoring and adjustment, as well as incorporating self-learning algorithms to optimize operating parameters over time.

Large-scale laundry facilities currently rely on a manual fabric color sorting process that is time-consuming and costly. This method also exposes workers to potential health hazards from contaminants on clothing. In addition, there is a need for an automated solution to help individuals with visual impairments or other disabilities quickly classify fabric colors. This project proposes and develops an automated “Fabric Color Sorting System” to address these issues by accurately identifying and separating white fabrics from colored fabrics.

HOW DOES IT WORK

The system provides precise identification and separation of white and colored fabrics. This innovative solution integrates several advanced components mounted on a lightweight aluminum frame.

• Keyence color sensors
• Photoelectric sensors
• Robotic cylinders
• Vacuum suction systems
• Mitsubishi PLC control
• Intuitive HMI touch interface

The system can process six samples (two white, four colored) in 55 seconds, automatically sorting them into designated bins. This automation reduces labor costs, increases operational efficiency, and improves worker safety by minimizing contact with contaminated materials. The system also creates a more inclusive environment by increasing accessibility for people with visual impairments.

This solution modernizes laundry operations and creates safer, more inclusive working environments

Falls and navigation challenges pose significant risks for elderly and visually impaired individuals, often leading to serious injuries according to the World Health Organization. While assistive devices exist, many lack the flexibility needed for daily use.

Nearly a million people navigate life with visual impairments in Vietnam, their world shaped by shadows and sounds rather than sights. Of the 900,000 affected individuals—1.2% of the nation’s population—two-thirds experience total blindness. The challenge is further compounded by poverty, with one in three unable to access sight-restoring treatments due to financial constraints. In rural areas, where information about assistive technologies is scarce, the need for innovative solutions is particularly acute.

Enter our groundbreaking smart glasses, inspired by nature’s own master of navigation—the bat. These glasses harness the power of echolocation, blending cutting-edge hardware with sophisticated software to create a “visual” world through sound.

How do they work? It’s brilliantly simple:

1. Power Up: With a simple switch, users activate the glasses’ built-in battery, bringing this assistive marvel to life.
2. Customized Sensing: A user-friendly dial allows for personalized distance settings, adapting the ultrasonic sensors to individual needs and environments.
3. Invisible Radar: The glasses emit ultrasonic waves that bounce off nearby objects. These returning waves are captured by a receiver, instantly calculating distances to potential obstacles.
4. Vigilant Guardian: When an obstacle is detected, a discreet buzzer alerts the user, providing an auditory “map” of their surroundings.

While revolutionary, our current prototype still has room for growth. We’re working on enhancing the power source for extended use, introducing voice and vibration alerts for more nuanced feedback, and refining the aesthetic design to blend functionality with style.

As we look to the future, we envision these smart glasses not just as a tool, but as a beacon of independence for Vietnam’s visually impaired community. By making the invisible visible through sound, we’re not just creating a product—we’re crafting a new way of seeing the world.
