บทคัดย่อ	A REAL-TIME MONITORING OF A CLOSED-LOOP WATER COOLING SYSTEM USING A WIRELESS ACOUSTIC EMISSION SENSOR : This thesis proposes a real-time monitoring of a closed-loop water cooling system using a wireless acoustic emission sensor. The proposed system comprises four major components, i.e. a preamplifier, a microcontroller-based analog-to-digital converter, wireless transmission modules and a graphic user interface. The preamplifier is implemented using BiMOS operational amplifier model CA3140 which provides high input impedance and high speed performance. The signal is subsequently digitized by STM32F4 microcontroller and transmits to the personal computer wirelessly via wireless transmission modules using XBee. The experiments show that the proposed system offers a cost-effective data acquisition system for an AE sensor to monitor a closed-loop water cooling system which can overcome the limitation on a long distance operation in order to utilize in the real world applications.
