It is an Embedded Solution which can be used with PLC device to convert its editable test reports (i.e. csv files) to non-editable test reports(i.e. pdf etc.) with proper formats. - Raspberry PI acts as an access point. It has its own web server with rich GUI and gives user friendly interface. - User can connect to access point and download non editable reports using GUI. - Device also takes backup of reports automatically and gives indication on memory exceptions.

This is an Internet of Things (IOT) where a microcontroller device was interfaced with multiple sensors like temperature, water level, humidity etc. -The controller module has a 3G GSM module interfaced which provides the high speed internet connectivity. Controller will collect the data from sensors and upload all the data to cloud. -Cloud is a live server which collects data from different controllers which are on the field. Cloud provides functionality to view the data on charts, tables, sorting of data, alert system, device configuration. -It has a Bluetooth connectivity over which it can communicate with a mobile device for troubleshooting and configuration. I have designed complete prototype which includes: - Component selection - Schematic and pcb layout design - Firmware development EDA Tool: Cadsoft eagle IDE: MPLabx, IAR Workbench for 8051
