This paper proposes an advanced system for process management via a credit card sized single board computer called raspberry pi based multi parameter monitoring hardware system designed using RS232 and microcontroller that measures and controls various global parameters. Various kinds of sensors are utilized in order to control and monitor the various kinds of hazards that occur during industrial process. The system comprises of a single master and multiple slaves with wireless mode of communication and a raspberry pi system that can either operate on windows or Linux operating system. The parameters that can be tracked are current, voltage, temperature, light intensity and water level. The hardware design is done with the surface mount devices (SMD) on a double layer printed circuit board (PCB) to reduced the size and improve the power efficiency. The various interesting features are field device communication via USB-OTG enabled Android devices, on field firm ware update without any specific hardware and remote monitoring and control. Remote monitoring is also performed by connecting a web server to the raspberry kit and establishing a secure wireless connection to all the sensors used. With the updated security channels one can continuously track the process occurring in industries.
