Build a Nighttime Elderly Motion Alert with Arduino Uno — Senior Movement Alert Kit

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

This kit transforms everyday electronics into a gentle caregiver's assistant. You'll assemble a circuit that turns on a soft white LED only when an elderly person moves in a dim room — giving you a non-intrusive alert that doesn't disturb their sleep. Perfect for hallway monitoring, bedroom safety, or simply staying aware without constant supervision.

What You'll Build

A compact prototype where a PIR sensor detects motion and an LDR checks ambient light. When it's dark and someone walks past, the LED glows for 30 seconds. The logic is simple: no false alarms during daytime, no harsh lights, just a peace-of-mind alert for caregivers.

What You'll Learn

• Reading PIR sensor output and setting trigger delay using on-module trimmers
• Using an LDR voltage divider to sense light levels and enable dark-only activation
• Wiring LEDs with current-limiting resistors for safe, long-lasting operation
• Combining two sensor inputs to create a real-world assistive device for elderly care

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Ideal for ATL Tinkering Lab students, CBSE Class 11–12 physics projects, and B.Tech ECE/EEE freshers prototyping for Smart India Hackathon or college assignments. Even families with children (ages 5–15) can build it together to create a meaningful gift for grandparents — combining simple circuitry with a deeply human use case.

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.
