Senior Movement Alert Kit v4
Build a Senior Movement Alert System with the Raspberry Pi Pico W – Capture Photos on Movement
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Monitor an elderly family member’s movement and automatically capture a timestamped photo when motion is detected. This kit turns a Raspberry Pi Pico W into a low-cost senior safety device that can alert you if a grandparent has been inactive for a set period—perfect for Indian households where elders live independently in the same home or require subtle, non-intrusive oversight.
What You'll Build
You’ll assemble a compact unit that uses a PIR sensor to detect movement in a room. When motion is sensed, the Pico W triggers the OV2640 camera over I2C, snaps a picture, and saves it with date and time on a microSD card. An OLED display shows real-time status, making it easy to see if the system is armed and when the last alert was captured. You’ll have a working prototype that can help you monitor a grandparent's activity without intrusive video feeds.
What You'll Learn
- Interface an HC-SR501 PIR sensor with a Raspberry Pi Pico W using MicroPython
- Configure the OV2640 camera module over I2C to capture still images on demand
- Program timestamp logic using the Pico W’s RTC and save files to a microSD card
- Design a real-time status display on a 0.96-inch OLED screen

Who This Kit Is For
If you’re a CBSE Class 11 or 12 student working on a computer science or physics project, a first-year B.Tech student in ECE or EEE exploring embedded systems, or a participant in the Smart India Hackathon building a frugal senior-care solution, this kit gives you everything to demonstrate a working IoT-based elderly monitor. It’s also well-suited for ATL Tinkering Labs and hobbyists from IIT, NIT, VIT, or BITS who want a practical introduction to Pico W and camera 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.
What if I get stuck during the build?
Scan the QR code inside the box to chat with our AI companion trained on this exact kit; you’ll get step-by-step help, and our WhatsApp support is available if you need a human eye.
Can I use this kit to monitor more than one room?
Yes, the PIR sensor covers a wide angle in one room, but you can easily extend the design by adding multiple PIRs to different Pico W GPIOs with minor code changes—our AI companion can guide that adaptation.
Does the system need an internet connection to work?
No, the kit works fully offline—motion detection, image capture, timestamps, and SD card storage all run locally. The Pico W’s WiFi is available for future expansions like push alerts, and the AI companion can suggest code for that if you decide to upgrade.
How long will the SD card store images before running out of space?
Storage depends on the card you use (not included). A typical 16GB microSD card can hold thousands of OV2640 JPEGs, giving you weeks of 24/7 monitoring. The OLED also shows a counter, so you know when to archive or clear files.
Elderly Care — PIR triggers Pico W to capture image from OV2640 over I2C and save to SD card with timestamp.
