Study on embedded system for voltage and current measurement using microcontroller and sensors

AbstractMicrocontroller is widely used in different sophisticated instruments as they are highly reliable and easily programmable as per our need .Real time monitoring of voltage and current has very wide range of applications. In this paper an experimental system based on Atmega 2560 microcontroller was developed. The main components of the system were Atmega 2560 microcontroller, voltage sensor and current sensor. In this paper data acquisition process between microcontroller and computer is also introduced. The method used for transferring data is serial communication.
