A hardware prototype of a high-sensitivity microbarometer infrasound sensor that detects low-frequency atmospheric pressure waves between 0.01 Hz and 20 Hz, built by engineering students.

Signing in saves it for your whole team — everyone on your invite link sees the same two entries. Anything you shortlisted while signed out comes with you.
Decomposed from what the description asks for. Nothing added.
Pressure Sensing Mechanism
Design the core hardware mechanism to detect low-frequency atmospheric pressure fluctuations.
Analog Front-End Electronics
Build low-noise electronic circuits to condition the captured sensor signals.
Environmental and Mechanical Enclosure
Construct the physical enclosure, transducer design, and a wind-noise reduction interface.
Pressure Equalization System
Implement a long-period pressure equalization system and temperature compensation.
Calibration and Testing Setup
Demonstrate laboratory characterization, noise floor measurements, and sensitivity estimation using open-market digitizers.
Both columns are read off the brief's own wording. Nothing here is inferred from the ministry's name.
The jury will evaluate your prototype based on laboratory characterization of the frequency response, noise floor measurements, sensitivity estimation, and stability testing.
A jury can still ask about these. Decide them deliberately rather than by accident.
Generated from the brief's own wording and the competition's published rules — never from a guess about what this ministry prefers.
Exact sensitivity numerical targets?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.
Required dynamic range?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.
Maximum power consumption limits?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.
Specific table of evaluation parameters referenced in the text?
The brief never answers this, so a panel will. Whatever you decide, say it the same way twice.
Has any part of this been shown at a previous event, hackathon or college project?
Each one is quoted from a gap in the brief, not a guess about your team.
Needs physical hardware
Listed as a hardware problem statement, so a working demo needs physical components you have to source yourself.
Needs data you may not get
Building specialized hardware sensors requires physical fabrication facilities and specialized equipment that students typically cannot obtain during a hackathon.
No measurable target
The description mentions an evaluation table but leaves it blank, omitting specific numerical thresholds for sensitivity and noise floor.
What the organisers attached, and what the brief assumes you can get.
Same organisation, same year. Reading two of theirs tells you more about what they care about than reading one.
Pick what you are about to do and copy the prompt. It carries the organisers' own wording, the constraints they never spell out, and an instruction not to invent requirements they never set.
Who has this problem, what already exists, and what you would have to find out.
The guidelines are explicit: your solution must not have appeared in any previous event or programme, of any sort. A recycled project is what a team under time pressure reaches for.
The brief asks for pressure sensing mechanism. How would you build that?
Decoded from SIH26144 itself — Design the core hardware mechanism to detect low-frequency atmospheric pressure fluctuations. The brief asks for it by name.
The brief asks for analog front-end electronics. How would you build that?
Decoded from SIH26144 itself — Build low-noise electronic circuits to condition the captured sensor signals. The brief asks for it by name.
The brief asks for environmental and mechanical enclosure. How would you build that?

Where does your data come from — a published source, one you collect, or one you generate?
No dataset is attached to this problem statement, so sourcing it is part of the work and nobody told you that.
Why not use what already exists? Name the closest thing to this that is already running.
A team that has not named the alternative themselves is answering this for the first time in the room.
Which single thing will you demonstrate end to end, start to finish, with nothing skipped?
Ours, not a rule: a narrow thing that fully works survives questioning better than a broad thing that half works. If nobody on the team can name it, that is the finding.
Show me this working: the jury will evaluate your prototype based on laboratory characterization of the frequency response, noise floor measurements, sensitivity estimation, and stability testing.
This is the evaluator read for your problem statement, decoded from the brief's own wording.
