This project aims to develop RFID reader. With the following scope can scan at least 15 cards save both entry and exit data display Welcome on the screen and add or reduce codes by yourself The test results show that the RFID scanner can scan both key cards and manually scan both in and out. The screen also shows Welcome when someone enters and shows thank you when someone shows that the developed scanner can be applied really slowly

Water became an important factor for propelling production process of any industries or factories and groundwater was option for production cost reduction especially in areas where had no surfacewater. B.Foods Product International Company Limited an affiliate of Betagro Group was located in Lop Buri Province to daily consume huge quantity of groundwater for production process in its factory. Measuring and recording levels of groundwater in 2 ground tanks related to volume of the water at time point of every 3 hours must continually be done every day in order to prevent lack of water fed into the factory that may impact of its production process. The main problem was caused of unexpected non-working of pumps. Knowing fluctuation of water levels could provide their immediate improvement and recover to avoid serious impacts. A microcontroller board could be employed to control groundwater volume in order that the company could closely follow up levels of groundwater in the ground tanks in real time and continuity. This study went on designing the microcontroller board for managing utility system and maintenance by using with level meter and wireless receiver and transmitter for testing working efficiency every 3 hours of each everyday during 1 February 2016 till 11 March 2016 totally 40 days. It was compared with those of same duration done manually. The findings revealed that the figured from 2 methods became similar and had very close relationship with each other. This could indicate that the simulated microcontroller board could be employed to automatically control groundwater volume efficiently. The company could bring it to appropriately trace levels of groundwater in the tanks in accordance with water usage behavior in each period of time for disruption of production process caused of insufficient quantity of groundwater. And this could be adaptable benefits for improvement of any organizations and also for any further studies

These dissertation is discussed development of Automatic Provision Paper Machine. By apply suction roller in the paper provision paper of size A4 to as a set and suture package control by microcontroller AVR MEGA 1280. Which the machine has 8 layer each layer has 50 sheets use the time for provision 40 second per minute that 1 set has 8 sheets. From the results of the equipment. It have some problem form suction rollers system. May be caused equipment in each is different an size roller or stiffness of spring and errors. Sensor is detect camshaft at moving through the disturbance of the light surround area with too much ability to detect lower. Which the repair and amend it
