Senior Movement Alert Kit with ESP32 + DHT22
Senior Movement Alert Kit with ESP32: Web-Controlled Elderly Monitoring System
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 a system that quietly monitors movement in a senior family member’s room, alerts you when something seems off, and lets you control lights, a fan, and a lock remotely — all from a web dashboard you build yourself. This kit gives you the hardware and AI guidance to create that peace of mind, turning an ESP32 into a full-featured elderly care station with OTA update capability.
What You'll Build
A complete elder-monitoring solution with a web interface that displays real-time temperature and motion data, and allows remote control of a door lock, lights, and a buzzer. You’ll assemble a sensor node that communicates with an ESP32 web server, accessible over WiFi, and mount everything inside a sturdy enclosure — ready to install in a loved one’s home.
What You'll Learn
- Integrate multiple sensors (PIR, DHT22, RFID) on an ESP32 platform and stream their data to a local web page
- Build a web dashboard using HTML, CSS, and JavaScript served directly from the ESP32, with live updates and control buttons
- Implement OTA updates to remotely upgrade firmware without physical access to the device
- Control high-power appliances safely using relay modules, flyback diodes, and proper power isolation with a buck converter
