The natural crab population is decreasing while the market demand is increasing. Crab farms face several problems in raising crabs as they can kill each other due to high density during the period of shell molting.

How does it work?
The farm is divided into small tubs to prevent the crabs from killing each other. The water supply to the farm is controlled by solubility sensors to ensure that only qualified water enters the farm.- The system is equipped with other sensors to provide water at an appropriate temperature to help the crabs reproduce. Light and humidity sensors, as well as solar panels, are installed to help farmers control their farm in a smarter way.

One of the goals of the technological revolution is to make life more convenient.
Smart homes allow us to live comfortably without having to worry about cooking, brewing coffee, ironing laundry or wasting electricity. Everything is automated. For this reason, our team has decided to build a Smart Home that fulfills some of these requirements.

How does it work?
Energy saving: Motion detection turns the light on and turns it off when there is no movement and it reduces light intensity when sufficient daylight illuminates the area.
Security: There is a sound alarm for incidents such as fires, earthquakes and flashing lights, indicating that an intruder enters.
The door locks and unlocks with a passcode.

Severe winters lead to the death of animals, livestock and poultry in villages, resulting in loss of income and investment for farmers. Our team proposed a project to build a community shelter, equipped with modern technology to reduce cold-related deaths.

How does it work?
We install sensors – to measure the outside and inside temperature – and heating systems. The indoor temperature is automatically adjusted to provide heat to the indoor station.

We also install automatic feed doors to provide food and water to the animals at specific times.

Last but not least, we install automatic cleaning and chemical spraying systems for the station. At the end of each day, the cleaning system will operate to clean the station, and spraying approved chemicals to protect the animals from diseases.

In agriculture, seed preservation plays a vital role in ensuring optimal plant growth and maximizing yields. Vietnam’s hot and humid climate poses significant challenges when it comes to storing seeds. In response to this issue, we propose a smart cabinet that is able to control air quality, humidity, temperature, prevent mold and unintended germination. This project aims to simplify seed preservation for farmers, using the internet of things: data is collected, processed and updated to https://www.adafruit.com via micro:bit.

How does it work?
UV light runs for 10 minutes daily to disinfect and prevent harmful bacteria and mold while fans adjust air circulation based on temperature sensors installed inside the cabinet. A dehumidifier activates when humidity is low and temperature and humidity data is regularly updated via an app on a tablet. Alerts are sent to users via the Telegram account if conditions exceed standard levels.

“Previously, we just saw a vending machine, but we didn’t know how it works. So we got quite curious and imagined, one day we can build a vending machine on our own” Chan Tran said. Our vending machine uses magnetic cards to scan, record and confirm identity of users (especially at schools). The USP being, that the machine can connect to the parents, so the parents are in control of what the studnts buy at school. That way, they can controle how much money is being spent and what the kids consume.

The farm has a water storage channel, which is used to water the leaves of the plants. When the humidity is below 65%, the drop irrigation system will be activated. The lighting and watering/irrigation systems are controlled via website. The roof works with automatic opening and closing depending on the light, temperature and rain sensors.

Bar fires often lead to a high death toll, because of suffocation, as there is no emergency exit.
Our group decided to develop a project called Automatic Emergency System, based on how it works on airplanes; oxygen masks release whenever there is a drop in cabin pressure.

In case of emergency/fire, the system will automatically release custom-designed safety masks (with reflective strips) onto the floor which the people in the room can grab and put them on first, before they find their way out.

In each room, the smoke detectors are connected to the central system. In case of smoke detection, it will set the alarms on, and automatically release all the fire escape ladders, so people find their way out via thee escape ladders and don’t have to jump out of the building, which in many cases lead to deaths or severe casualties.
