Aquaponics Kit v4 — Speech Recognition with Raspberry Pi Zero 2W

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine telling your aquaponics setup to switch on the water pump or activate grow lights, and it responds instantly — no cloud dependency, no lag. This kit puts offline speech recognition directly on a Raspberry Pi Zero 2W using vosk, so you can build a voice-triggered relay controller that works entirely offline. Ideal for school labs, college mini-projects, and anyone exploring edge AI automation.

What You'll Build

You’ll wire the USB microphone and 4-channel relay to the Pi Zero 2W, insert the pre-loaded MicroSD card, and boot into a system that listens for spoken commands like “pump on”, “lights off”, or “status”. The vosk engine recognises these offline and sends signals to the relays, letting you control real hardware with your voice. It’s a complete voice-activated automation demo that fits neatly onto a breadboard or small enclosure.

What You'll Learn

• Deploy offline speech recognition with vosk on a resource-constrained Raspberry Pi Zero 2W
• Interface a USB microphone and parse voice-to-text commands in Python
• Control a multi-channel relay module from GPIO to switch external AC or DC loads
• Integrate voice triggers into a functional automation loop for real-world applications
