  1. Areas of Research:
    • Embedded System Technologies
    • Sensor and Sensing Technologies
    • E-Nose and E-Vision Technologies

  2. Sensor Hub and related projects:
    Title of Project: Development of Handheld E-Nose
    Objective of the Project: The objective of the project is to design and develop a hand-held E-Nose system. The target device will be used primarily for quality testing of finished tea and tea- fermentation process
    Brief outline of the project with specific technology fall-outs:
    1. A low power, portable, low cost, battery operated and small device will be targeted.
    2. MOS sensors indigenously developed by Sensor Hub, Kolkata will be tried as sensor elements, namely, 1.5% Au-SnO2 ,1% Au-SnO2 ,.5% Au-SnO2,1% Pd-SnO2 ,Fe2O3,1% Ag-SnO2 ,1% Pt-SnO2 ,1% La-SnO2 ,1% Cu-SnO2 ,SnO2. Figaro make imported sensors will also be used in the development namely, TGS-823, TGS-832, TGS-2600, TGS-2610 and TGS-2620.
    3. A simple, low-power, lightweight mechanical arrangement will be developed for sniffing and purging operation of the sensor assembly. The system may also work with 220V ac.
    4. Detachable Sensor unit with arrangement of sniffing and purging
    5. Data acquisition and processing will be done using a suitably chosen micro-controller, preferably, a 16-bit PIC 24FJ256DA210 microcontroller.
    6. A small graphical touch-screen display will be used for display of results, reports and data entry. The microcontroller is having the inbuilt Graphics Controller.
    7. Memory card of 2GB or more, FAT 32 file system will be used for data storage and keeping the log of data.
    8. A PC interface will be developed that will be used to dump these data on to the PC for archival and further analysis.
    9. The sensor assembly will draw power from a rechargeable, portable battery unit and may also operate through a 220 V ac.
    10. The handheld unit will operate with rechargeable battery and it also has the option to operate with mains power supply 220V ac.
