ReactaPair™ – Dual-Trigger Sensor Kit (Sound + IR)
Precision Triggers. Compact Deployment.
The ReactaPair™ Dual-Trigger Sensor Kit delivers a powerful 1–2 punch of environmental reactivity: precision sound detection and fast infrared object sensing — all in a portable, Grove-compatible package. Designed for smart infrastructure developers, automation engineers, and diagnostic field techs, this bundle gives you essential tools to build systems that respond instantly to real-world stimuli.
From threshold-based alerts to robotics and automation prototypes, ReactaPair™ empowers you to build, test, and deploy fast — with no bulky overhead or cloud lock-in.

📌 Legal & Usage Notice:
ReactaPair™ is designed for rapid prototyping, diagnostics, and educational applications. It is not certified for regulated industrial or safety-critical use cases without additional third-party certification. Users are responsible for final deployment configurations, including safety thresholds and calibration. No proprietary software or subscription is required.
❓FAQ
Q: Can I use this to trigger actions based on sound?
A: Yes. The sound sensor outputs an analog signal you can use to activate relays, lights, or other devices based on a customizable threshold.
Q: Is the IR sensor only for line-following robots?
A: Not at all — it's useful for object detection, counting systems, edge triggers, and more.
Q: Does it work with Raspberry Pi?
A: Yes, with a Grove Base Hat or GPIO-to-Grove adapter.
Q: Is the included guide beginner-friendly?
A: Yes. The guide walks you through wiring, logic setup, and sample projects — no guesswork or code-hunting required.
Q: Is this safe for field use?
A: Yes, but housing is recommended for outdoor or long-term exposure. Always test thoroughly before final deployment.
