Objective(s) & Technology Involved

Our objective is to develop an application, called तीर्थयात्रीसहायक, using Sensor-Mobile-Cloud technology. This technology integrates sensors, mobiles and cloud infrastructures into uniform platform for sensing, collecting, and analyzing human movement

Salient Features

  • Multiple Sensing Technology: PSU can scan Wi-Fi, Bluetooth Classic and Bluetooth Smart Devices simultaneously.
  • Customize Sensing Range and Channel: Provision for increasing Wi-Fi scanning range approx. from 10 meters to 1000 meters, and changing the Wi-Fi channel from 1 to 13.
  • Enhanced Sensing Period: Long life scanning period of Wi-Fi and Bluetooth devices by using external battery through Y-cable.
  • Energy Efficient Data Upload: File size (maximum records stored in file) for uploading to the cloud server can be customized as per the network condition (availability of Wi-Fi/3G).
  • Scalable Server Client Architecture: Use of Rest API and Django based cloud server for rapid configuration of the proposed system. The architecture supports light weight requests and responses to handle huge amount of transactions between client and server.
  • Accurate Outdoor/Indoor Location Tracking: Use of Google Location API for optimizing the location accuracy.


To test the PSU performance and accuracy in real scenario, we went to Haridwar and tracked the pilgrims’ smartphones using PSU.
