This project is intended as a teaching medium air conditioning system and simulation of air conditioning system problems. Some of them have been modified to suit their teaching needs. Arduino microcontrollers are used to control the system. By starting the study of the air conditioning system thoroughly. The microcontroller is written to control the operation of devices like the air conditioning system when the system malfunction. It will be used to analyze the problems of air conditioning. The experimental set will display the voltage and current. The connection points of the air conditioning problem analysis. When the symptoms are bad. The analyst can solve the problem by connecting or pressing the button of the device. The results of the project. The test will measure the difference of the air conditioning unit. And read the amount of current and volume in the system. To diagnose abnormalities and choose a solution to the problem from the kit system that can be displayed to solve the problem that the analyst was correct or not with the LED status light. Based on the performance test a demonstration kit for the demonstration of efficiency of the air conditioning system was provided to 10 experienced air conditioning technicians. 80s of issues. The reliability of the demonstration set and the efficiency of the simulator case study of the electrical system in air conditioning systems is acceptable

Nowadays the measurement technologies are continually growth in advanced. These can be seen in the developed and developing countries that research and develop the products which support the consumer behavior and/or country economy ic growth. However some advanced products are very expensive such as pH meter. Therefore this thesis develops the pH meter which allows the acid-base test of the water and it can be supported the agriculture. The proposed pH meter is included the pH pen sensor temperature sensor water level sensor. The proposed meter can measure the acid-base of the water by sending SMS alert signal via GSM module to the mobile phone of the farmer. As can be seen this thesis can prevent and solve the effect of the high acid-base of the water that possibly flows into the agriculture farm via using SMS alert signal of the mobile phone of the farmer.

This research presents a bamboo chopsticks machine with automatic control system. The production of bamboo chopsticks the current will be cut to get the machine to enter the bamboo chopsticks using the machine. The machine will hammer bamboo rotation of the electric motor. The AC motors with high power. Currently the production of chopsticks mostly small businesses. Lower costs which resulted in lack of effective security. This research presents the design and techniques with bamboo chopsticks production automation. The objective is to make the production of bamboo chopsticks are secure and compliant. To increase productivity and reduce the danger of the machine. In designing the Arduino technology is used in the development of electronic prototypes designed to be user for both hardware and software advanced application control equipment used in the production of chopsticks for safe to use on the incidence of danger from the use.

The objective of this research was to compare the quality of Kanomchan which replace rice flour with Homnil rice flour Riceberry rice flour and Sangyod rice flour and to study the quantity of modified starches used in frozen Kanomchan products. Sensory evaluation of 30 panelists using 9 points Hedonic Scale. It was found that the panelist preferred Kanomchan that was made from Sangyod rice rather than the Kanomchan made from Riceberry rice flour and Homnil rice flour (p≤0.05). In the recipe of Kanomchan consist of 40.98% coconut milk 37.30% flour 10.65% cassava starch 9.02% cassava starch and 2.05% rice flour. Then using Sangyod rice flour in Kanomchan products to study modified starches suitable quantity for frozen Kanomchan products by three standards. Constitute 1% 3% and 4% by replacing of cassava starch. And compared with base recipe that not add modified starches. Then Kanomchan was freeze at -18 °c for three days. Before defrost with microwave and heated with 640 watts of microwave power for 2 minutes. The result found that frozen Kanomchan product which adding 3% modified starch had the most sensory points in every attributes. Except taste score texture (toughness) and overall score more than non-modified starches recipe (p>0.05). Then study three types of hydrocolloids. (guar gum gum Arabic and carrageenan) for develop quality of frozen kanomchan products by add hydrocolloids 0.1% for amount starches in frozen kanomchan products that using. Then freeze at -18 °c and reheat with microwave which had 640 watts of microwave power for 2 minutes. The result is guar gum had the most of linking points good texture that suitable with frozen Kanomchan products than caragenan and gum arabic. Results of the selection of the pattern of Kanomchan in packaging. By all experts choose a rose mold. and the packaging style numbrr 1 with the accompanying reasons name and the product brand prominently easy to remember beautiful colors look appetizing and linked the Thai dessert.

The objectives of the Development of Thai Song Dum Fabric Pattern by Computerized Embroidery Machine for Living Room Products are as follows 1) to develop Thai Song Dum fabric pattern with computer machine for living room products and 2) to study the satisfaction of consumers towards the pattern of Thai Song Dum fabric with computerized machines for living room products. The sample group consumers who visit Bang Luang Market Thung Bua Daeng Floating Market and Lam Phaya Floating Market by using 50 consumers in each market including 150 consumers in 3 markets used to analyze data such as mean percentage standard deviation and analyzed the data by using computer software. The results of the research showed that most consumers were satisfied with the overall picture at a high level. The satisfaction of consumers Bang Luang market the first is the living room product the Dok Priew pattern with an average of 4.47. The Dok Chan Lom pattern has an average of 4.40 and the Dok Bua pattern has an average of 4.37. The consumer satisfaction Thung Bua Daeng floating market. The first is the Dok Bua patterned living room product has an average value of 4.56. The Dok Chan Lom pattern is 4.50 and the Dok Priew pattern has an average of 4.44. The consumers satisfaction Lam Phaya floating market is the Dok Priew has an average of 4.49 the Dok Chan Lom pattern is 4.48 and the Dok Bua pattern is 4.37.
