Senior Movement Alert Kit with ESP32 + Relay
Senior Movement Alert Kit – ESP32-Based IoT Elderly Care Automation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Create a comprehensive elderly care monitoring and alert system that senses movement, ambient light, temperature, and humidity across multiple rooms. The ESP32 microcontroller drives 8 independent relay zones to control lights, buzzers, or HVAC, all managed through a Node-RED dashboard you build from scratch. All sensor data is automatically logged to an SD card with precise timestamps, and the entire firmware can be updated wirelessly without opening the enclosure — exactly the kind of reliable system needed in senior homes.
What You'll Build
You will assemble and program a wall‑mounted unit that detects falls, unusual inactivity, or uncomfortable environmental conditions. PIR sensors track movement in three zones; the DHT22s monitor climate; the BH1750 adjusts relay‑driven lights based on ambient brightness. Data streams live to your Node-RED UI, where you can remotely trigger alerts, switch appliances, and review historical logs. OTA updates let you refine logic after deployment without disturbing the system.
What You'll Learn
- Interface ESP32 with multiple I2C and digital sensors, managing shared buses with minimal latency
- Design a Node-RED dashboard with real‑time charts, relay toggles, and email/Telegram alert nodes
- Implement Over‑The‑Air firmware updates using ArduinoOTA, including rollback safeguards
- Engineer 8‑channel relay control with flyback diode protection and manual override capability

Who This Kit Is For
This kit is built for B.Tech ECE and EEE students developing final‑year projects with real‑world social impact, and for teams at Smart India Hackathon tackling assisted living challenges. It’s equally suited to IoT enthusiasts and embedded engineers who want to prototype a reliable elderly care product without sourcing components from ten different vendors. If you’ve worked with Arduino or ESP32 before and are comfortable soldering, you’ll find this project deeply rewarding.
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 launch the AI companion trained on this kit’s circuitry and code. For trickier issues, our WhatsApp support responds within a few hours.
Can I receive phone notifications when movement stops?
Yes. The Node-RED dashboard you build can trigger Telegram or email alerts based on PIR inactivity thresholds, so caregivers are notified immediately.
Does the kit include everything needed to solder and assemble?
Absolutely — soldering iron, solder wire, prototype boards, enclosure, and even the 1N4007 diodes are included. You only need a computer to upload code.
Can I add more sensors or relays later?
The system is designed for expansion. Node-RED flows and ESP32 code are modular; you can add extra I2C sensors or daisy-chain relay boards with the included buck converter providing ample current headroom.
Elderly Care — ESP32 controls 8 relay zones from Node-RED. All sensors auto-logged. OTA updates enabled.
