FAQs about PRAVAAH

Why does it use both a Raspberry Pi and an Arduino?

The Raspberry Pi 5 handles heavy data processing, edge-AI, and complex networking, while the Arduino handles real-time deterministic I/O and acts as a hardware watchdog to reboot the system if necessary.

Is it protected against electrical surges?

Yes, the custom electronics board features galvanic isolation to protect the core compute from sensor-side voltage spikes.

Can it trigger external devices like sirens?

Absolutely. It features programmable NO/NC relays allowing automated control activation of external infrastructure.

How does the dual validation work?

PRAVAAH uses both microwave radar velocity and an integrated Full HD (1080p) AI optical camera to track surface velocity simultaneously. This provides unmatched cross-validation of measurements.

What is the maximum measurement width for the camera?

The varifocal lens and AI tracking algorithm are optimized for river and drain widths up to 20 meters.

Is the enclosure waterproof?

Yes, the aluminum body and polycarbonate lens cover carry an IP67 rating, meaning it can easily survive heavy downpours and harsh outdoor industrial environments.
