Abstract

This paper presents the design and construction of a liquid mixer machine controlled by microcontroller. It controls four 12-volt solenoid valves via 4-way solenoid valves. There are 4-type liquids to mix together by pressing the switch selector. The LCD display shows the amount of required liquid mixture. When the ingredients are suitable, the liquids will flow into the container. In addition, the four liquid level sensors are also available in the system. The proposed liquid mixer machine has been constructed and tested. The results are shown that the performance of the machine is satisfactory.

Abstract

This paper presents the prototype of temperature and voltage detection and notification system in server room. The case study is at SK Polymer Co., Ltd. The system displays the temperature, humidity, voltage and current values on the LCD display. The results on the windows application are the temperature and status of the AC power failure. The server room is high or low temperatures and/or power failure. Then, the system automatically notifies the phone and e-mail to the server administrator. The system solves the old system used by staff to check only during office hours. However, at the beyond the operating hours, nobody can report the situation to the administrator and it will cause damage to the server. The test results of proposed system are shown that it can be displayed the value of temperature and AC power status on the LCD display and the developed application. The system can be alerted by the phone number and E-mail when some mistakes occur.

Keywords: temperature, voltage, detection

[fruitful_tab title=”2. Design and Construction of Seafood Kanomkrog Maker Controlled by Microcontroller”]

Abstract

This article presents the design and construction of seafood kanomkrog maker controlled by microcontroller. The appropriate amount of seafood kanomkrog mixing flour dropped into each hole of the kanomkrog cooking pan is controlled by microcontroller. Four sets of 13 holes kanomkrog cooking pan are included in this machine. The rotation of kanomkrog cooking pan to facilitate the mixing flour dropping and the return to its initial position are made by a DC motor controlled by microcontroller. The digging out of kanomkrog from each hole of the cooking pan is done manually in order to serve variety of orders to the customers conveniently. This proposed machine is constructed and tested and its performance is demonstrated to be satisfactory.

[fruitful_tab title=”5. Tunable Gm-C Floating Capacitance Multiplier”]

Abstract

This paper presents a realization of Gm-C floating capacitance multiplier. It employs MOS transistors as transconductors and only one grounded capacitor. The circuit offers the attractive features of simple configuration, electronically tunable capacitance multiplication factor, low sensitivities to variation of active and passive elements and suitability for integrated circuit implementation. The parasitic effects of the transconductors on the proposed floating capacitance multiplier are investigated. The performance of the proposed circuit is demonstrated on second-order band-pass filter. The PSPICE simulations using TSMC 0.18 µm CMOS process parameter are also given to confirm the theoretical analysis.

Keywords— floating capacitance multiplier; grounded capacitor; transconductor; high-pass filter; band-pass filter
