Design and implementation of Remote Terminal Unit on Mini Monitoring Weather Station Based on Microcontroller

In the previous research, a single master-multi slave microcontroller communication method has been developed. The microcontroller is able to communicate using unicast communication, i.e. the master gave orders to one slave address via the master-slave network that has star topology. Then the slave who has the same address which is requested will respond or take action in accordance with the master command. This paper will explain the use of a single master — multi slave communication method in a Remote Terminal Unit (RTU) of Mini Monitoring Weather Station Based on Microcontroller.
