CHAPTER 1 INTRODUCTION

Today, with the development of science and technology, the need for people is Increasing in many areas of social life This includes the need for a comfortable and smart life This has motivated designers and manufacturers to create products that meet this convenience and intelligence One of them is a smart dryer In developed countries, its use is very widespread and popular, but in developing countries, including Vietnam, there is a tendency to find suspicious and shiny pine trees there The other side of development: Modern development of houses and apartment complexes with small areas is still limited, so it is very necessary to be compact and meet the requirements, especially apartment buildings The dryingore, owning a smart drying rack will not consider the surface area of the balcony or location A very small balcony can also install a smart drying rack In addition, it also helps us get rid of problems when drying clothes, such as convenient high-level settings for many different ages, and additional integration Roof structure, drying fan help dry clothes easily and conveniently, protecting clothes from the effects of bad weather such as rain and humidity High humidity helps clothes dry faster Based on this need and open market, | started researching, designing, and manufacturing smart clothes drying racks And in this specialized project, I will present the process

of researching, designing, and manufacturing smart drying racks Specifically, 1 will start by analyzing the smart dryer market Then come up with the idea of improving smart dryers From this idea, we started designing the suspension system and control system to create this smart dryer The above contents will be presented in detail in the project During the design and production process, errors cannot be avoided I look forward to receiving valuable comments from my teachers to help

me further improve my project

It is estimated that in the capital Hanoi, there are about 20 apartment and condominium projects being implemented Some names that can be mentioned here are: VinHom City, Royal City, Vincom Ba Trieu, Novaland Sunrite City, Sky Garden, etc

Trang 17

Figure 1.5 Sky Garden 3

Apartment buildings appear more and more, helping people have more place resident But also main from now which entails are not little problems subject, especially in personal life Because the living space of an apartment is not much, with a basic Vietnamese family of 4 members, it is necessary to take advantage of are not time real brand fruit new yes can born Hentai one-way good Okay These Personal activities, especially drying clothes, have become one of the difficult problems for many households They make good use of the space to perform this, but see it seems not brand very fruity We can see people scene live zones apartment dry trousers shirt like how? live (Picture 1 6) No time born Hentai is occupied quite a lot for drying clothes, creating a bad scene for the urban area Not yet many households do not even have a place to dry their clothes, they must dry in makeshift place (Figure 1.7), where there is little wind and light, this causes the clothes to become moldy and uncomfortable for the wearer

s* The Internet of Things (IoT) plays an important role in modern life from many different aspects:

® Convenience and Time Savings: IoT allows devices to connect to each other and to the internet, creating a smart environment that saves time and productivity For example, smart home systems can automatically adjust lighting, temperature, or even the procurement of necessary goods through sensors and automated systems

® Seamless Connectivity: IoT helps connect everything from personal devices like smartphones and smartwatches to large industrial devices like machinery and medical equipment This creates a seamless, intelligent, and easily managed environment

e Enhanced Safety and Security: loT provides opportunities to improve security and safety For example, a smart home security system can warn when there is a risk of intrusion, or an unusual incident occurs

® Data and Analytics: IoT devices generate large amounts of data, providing important information to better understand user patterns, habits, and needs Analyzing this data can support smarter decision making

Trang 20

Faced with clothes born problem and improved available huge potential market demand, clothes drying racks were born to meet life's needs With increasingly modern life, people's lives are getting better and better, but dried products are also increasingly improved and transformed into many different types Next, we will learn about the types of dryers available on the market

Figure 2.5 Lora transceiver module sx1287 433mhz 10km UART LoRa (Long Range) is a wireless communication technology used to transmit data over long distances without requiring large amounts of power LoRa SX1278 433 MHz module is one of the popular modules based on Semtech's SX 1278 chip, designed to operate at 433 MHz

Trang 33

“* Main function LoRa (Long Range): LoRa technology allows data transmission at longer distances than many other wireless communication technologies without requiring large amounts of power This is suitable for oT (Internet of Things) applications or applications that need remote connectivity

UART Interface: The LoRa $X1278 module often has a UART (Universal Asynchronous Receiver-Transmitter) interface, which is a common interface for data transmission in microcontrollers or microprocessors The UART interface makes it easy to connect to other microcontrollers or microprocessors via TX/RX pins

Communication distance: This module is advertised as capable of transmitting data up to about 10km (depending on environmental conditions and configuration)

Flexible configuration: LoRa SX1278 module can be configured through AT commands or through direct programming

Applications: LoRa SX1278 modules are commonly used in oT projects, remote monitoring systems, wireless communication between devices at long distances, and in wireless sensor network applications

Trang 34

Transmission power: information about transmission power, receiver sensitivity, and parameters related to transmission performance

VCC/VDD: Power supply for the module (usually 3.3V or 5V depending on the module's requirements)

RESET: This pin is often used to reset the LoRa SX1278 module SPI Interface: If the module supports the SPI interface, there may

be pins such as MOSI, MISO, SCK (Clock), and/or other pins related to the SPI interface

Trang 36

e TX (Transmit) and RX (Receive): These are UART pins to transmit and receive data through the serial interface They are used to connect to a computer or other microcontroller

e CH PD (Chip Power Down): This pin is used to control the operation of the chip, usually needs to be connected to a 3.3V source to activate the chip

e GPIOO and GPIO2: These pins are often used during firmware flashing or in special boot states

Trang 37

e GND pin (Ground connection): This pin is connected to the ground connection of the power source
