India is moving from “import and integrate” to “design, characterise, and deploy.” Semiconductors are part of that story, but so are the sensors that give them purpose. To accelerate this shift, ELCIA (Electronics City Industries Association) and VSD (VLSI System Design) are launching the Sensor Characterisation Hackathon 2025. The goal is clear: push affordable sensor modules to *Technology Readiness Level 8*—and show the data that proves it. What makes this different? • Participants must log at least 24 hours of clean, time-stamped, field data—accuracy, drift, uptime—then publish everything on GitHub. • The cost cap is tight (₹8 000 total hardware), mirroring real-world constraints. • Top teams demonstrate live at IIIT Bangalore during the ELCIA Tech Summit, alongside industry veterans shaping India’s semiconductor roadmap. Whether you’re a student, a startup team, or an engineer looking for a challenge, this is a chance to convert raw readings into proof—and add a repository of reproducible results to your portfolio. Registrations open 20 June. Details here: https://elciatechsummit.in/hackathon-2025/ See you where data meets design.
