IMO MARPOL Annex VI regulation has been set for global application to reduce the negative consequences of ship gas emissions SOx, NOx, and CO2. To enforce the regulation, real time gas emission monitoring system is in need. The system in this paper consists of a microcontroller, gas analyzers, sensors and Xbee radio module. The data acquired from the sensors and gas analyzer is transmitted usin...

In order to simplify the device of modulation and demodulation of 2FSK, a 2FSK modem based on the microcontroller AT89C51 was designed. This modem is mainly composed of an AT89C51 microcontroller, a simple two order passive low-pass filter, and a shaping circuit. Modulation is achieved on the basis of the principle of pulse width modulation (PWM). By executing PWM signal generating program, a d...

In this study, parallel connection of synchronous generators has been achieved automatically by the monitoring parallel connection conditions with the microcontroller. For this reason, two synchronous generators which are rotated with direct current motors have been connected in parallel. Firstly, the conditions required for parallel connection has been observed with measuring tools. Then, a mi...

This proposed system uses an ultrasonic module interfaced to a microcontroller of 8051 family. An ultrasonic transducer comprising of a transmitter and receiver are used. The transmitted waves are reflected back from the object and received by the transducer again. The total time taken from sending the waves to receiving it is calculated by taking into consideration the velocity of sound. Then ...
