Palaniappan %J Advanced Computing : an International Journal %D 2012 %I Academy & Industry Research Collaboration Center (AIRCC) %X The Accurate measurement and analysis of pH data is necessary for a multitude of applicationsranging from agriculture sector to clinical laboratories. Preferably an inexpensive hand-held unit isneeded for these applications. This paper presents the sensor data acquisition and data logging systemincluding the details of its construction, capabilities and applications. PIC microcontroller has in-builtADC, which samples the output pH level measured by a pH meter. %K Embedded System %K MPLAB %K PIC Microcontroller %K pH meter %K RTOS. %U http://airccse.org/journal/acij/papers/0112acij04.pdf
