Problem & Constraints
Researchers in remote coastal areas need to enter multi-parameter sensor readings with high precision GPS location tagging, where network signals are unreliable.
Technical Implementation
Engineered an offline submission cache that queues sensor logs and geotags them with device hardware GPS. Developed a GIS station map with Google Maps API and an admin verification queue to audit readings before publishing.
Technical Highlights & Innovations
Interactive GIS Water Monitoring Map tracking 17+ regional stations across Bangladesh
Multi-parameter sensor measurement entry with automated device GPS location tagging
Role-based verification queue & admin status workflow dashboard
Historical water quality trend charts tracking salinity, EC, and temperature
