Senior Movement Alert Kit with Arduino Uno: GSM Phone Call Alert for Elderly Safety

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 your elderly parent at home alone — and you receive a phone call within seconds of unexpected movement. This kit lets you build exactly that system, using an Arduino Uno, a PIR motion sensor, and a GSM module to automatically dial your number when an intruder is detected. It bridges real‑world safety with hands‑on electronics learning, even if you’ve never coded before.

What You'll Build

A fully functional alert device that sits in a room and watches for motion. When the HC‑SR501 sensor detects infrared change, it instantly lights a red LED and commands the SIM800L module to place a voice call to a pre‑saved phone number. No Wi‑Fi, no app — just a standard 2G SIM card with calling credit. You’ll end up with a compact prototype that can be placed in an elderly relative’s room to summon help the moment someone enters.

What You'll Learn

• How PIR sensors detect infrared heat changes and output a digital signal
• Wiring and coding an Arduino to trigger GSM voice calls via AT commands
• Using an LM2596 buck converter to supply stable 4V to the power‑hungry SIM800L
• Debugging serial communication and handling capacitor‑smoothed power for reliable GSM operation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is built for Indian students in classes 6–10 crafting a science exhibition model, ATL Tinkering Lab innovators exploring IoT for social impact, and families who want a practical caregiver alarm. It requires zero prior electronics knowledge — the build is gentle enough for a 10‑year‑old with an adult nearby, yet concept‑rich enough to anchor a CBSE Class 12 computer science project on embedded systems. Even B.Tech ECE beginners will value the hands‑on lesson in GSM module integration.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
