In general, people use measurement devices which have analog gauge such as speedometer, barometer, and etc. to measure various values. However, analog gauges can cause problems with accuracy and reliability, since people measure the values directly through the needle of gauge. To solve these problems, we propose an ADC system to improve measurement accuracy and reliability more than analog devices. The system can extract measured value through image processing using OpenCV libraries. And, we increased user access to the implanting system in a portable device.
