This project presents the development of a "Smart Cat House" using Internet of Things (IoT) and image processing technology to facilitate and enhance the safety of cat care for owners. The infrastructure of the smart cat house consists of an ESP8266 board connected to an ESP32 CAM camera for cat monitoring, and an Arduino board that controls various sensors such as a motion sensor in the litter box, a DHT22 temperature and humidity sensor, an ultrasonic water and food level sensor, including a water supply system for cats, an automatic feeding system, and a ventilation system controlled by a DC FAN that adjusts its operation according to the measured temperature to maintain a suitable environment. There is also an IR sensor to detect the cat's entry into the litter box and an automatic sand changing system with a SERVO MOTOR. All systems are connected and controlled through the Blynk application, which can be used on mobile phones, allowing owners to monitor and care for their pets remotely. Cat detection and identification uses image processing technology from the ESP32 CAM camera in conjunction with YOLO (You Only Look Once), a high-performance object detection algorithm, to detect and distinguish between cats and people. Data from various sensors are sent to the Arduino board to control the operation of various devices in the smart cat house, such as turning lights on and off, automatically changing sand, adjusting temperature and humidity, feeding food and water at scheduled times, or ventilation. The use of a connection system via ESP8266 and the Blynk application makes it easy and convenient to control various devices. Owners can monitor and control the operation of the entire system from anywhere with internet access.
ในปัจจุบัน ผู้คนจำนวนมากเลือกเลี้ยงแมวเป็นเพื่อนคลายเหงา แต่ด้วยภาระหน้าที่การงาน การเรียน หรือธุระส่วนตัว ทำให้หลายครั้งเจ้าของไม่สามารถดูแลแมวได้อย่างใกล้ชิดตลอดเวลา ก่อให้เกิดความกังวลใจและเป็นห่วงสัตว์เลี้ยงที่บ้าน ปัญหาเหล่านี้เป็นแรงบันดาลใจให้เกิดแนวคิดในการพัฒนาบ้านแมวอัจฉริยะ (Smart Cat House) เพื่ออำนวยความสะดวกและตอบโจทย์ความต้องการของผู้เลี้ยงแมวในยุคปัจจุบัน บ้านแมวอัจฉริยะเป็นระบบที่ถูกออกแบบมาเพื่อช่วยให้เจ้าของสามารถติดตามและดูแลแมวได้จากระยะไกลผ่านแอปพลิเคชันบนมือถือ โดยภายในบ้านแมวอัจฉริยะจะมีระบบต่างๆ ที่ช่วยอำนวยความสะดวกสบายให้กับทั้งเจ้าของและแมว อาทิ ระบบควบคุมการให้อาหารและน้ำ ระบบจัดการกระบะทราย ระบบควบคุมอุณหภูมิ และระบบกล้องวงจรปิด เป็นต้น ทำให้บ้านแมวอัจฉริยะเป็นทางออกที่ตอบโจทย์สำหรับผู้เลี้ยงแมวที่ไม่ค่อยมีเวลา แต่ยังคงต้องการดูแลสัตว์เลี้ยงของตนให้มีความสุขและมีสุขภาพแข็งแรง

This study aimed to evaluate the optimal edible coating formulation for 'Namdokmai Sithong' mangoes by incorporating 10% gum arabic (GA) with mangosteen peel extract (MPE) at varying concentrations (1%, 3%, and 5%), compared to a control treatment (distilled water). The coated fruits were stored at room temperature for 14 days, and their physicochemical properties were assessed. The findings indicate that the application of GA (10%) combined with MPE effectively mitigated color changes in mango flesh, suppressed disease incidence, and preserved fruit firmness. Additionally, the coating significantly delayed alterations in total soluble solids (TSS), titratable acidity (TA), vitamin C content, carotenoid levels, and phenolic compounds. Among the tested formulations, GA (10%) + MPE (1%) exhibited the highest efficacy in extending shelf life, maintaining fruit quality, and enhancing surface gloss.

This project aims to introduce an Automated Vertical Metal Sheet Storage System. The project is aimed at teaching how to make an Automation Vertical Metal Sheet Storage System with the integration of microcontroller devices. The project is divided into two main sections, which are the structure and control systems of the Automation Vertical Metal Sheet Storage System that will be designed and drawn through a computer program and constructed using major aluminum structures upon completion of their actual sizes outlined in the programs. Also, a Microcontroller control system using GX Works 2 program from Mitsubishi PLC has been designed for this purpose where it controls up and down movements as well as sideways movement of the pallet. It also has a weighing capability along with touch screen display for displaying information about the steel plates and controlling the Automation Vertical Metal Sheet Storage System with safety light curtain that protect users safety. These tests have shown that the machine operates normally. There are few mistakes whose rates fall within those expected by humans.

Currently, the issue of developmental writing disabilities in children is a matter of great importance for school-age children. Diagnosing whether a child has developmental writing disabilities relies on writing skill assessments, which are administered to those seeking diagnosis and evaluated by medical professionals or experts. However, there are still limitations in the diagnostic process, which depends heavily on expert physicians, leading to a high demand for human resources. To address this, we have developed a method for scoring writing skill assessments using image processing technology, based on existing scoring criteria. Currently, three criteria are used for scoring: writing position, article format, and copying speed. We have also created a web application to make the system more accessible and easier to use.
