Pic Controller Based Process Control System Using GSM
Devices with microcontroller are widely used in industrial field. The authors use network interface for connecting more than one device for parallel control. Here, they present a design of PIC controller based embedded RS 485 interface. In this design the RS 485 module can be converted into network interface to obtain connectivity with the device. The design mainly consists of process control unit, RS485 communication module and GSM communication module. In the design the data can be transmitted from industrial device to process control unit and also data can be transmitted on mobile through GSM modem, when administrator requests for data.
