FAQs about TARANG

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

The Raspberry Pi 5 handles heavy data processing, edge-AI (like TensorFlow Lite models), 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 like the Rakshak EWS.

What is the maximum data storage capacity?

It comes with a 128 GB onboard microSD card by default and supports optional USB SSD expansion for massive edge data vaults.

How secure is the data transmission?

It supports secure boot, device authentication certificates, MQTT over TLS 1.2/1.3, and optional encrypted storage to ensure data integrity.
