Portable IoT-Based Smart Mini Refrigerator for Medical Use
Project Description:
-
Uses Peltier Module (TEC1-12706) for cooling.
-
Real-time temperature monitoring using a DHT22 or DS18B20 sensor.
-
Controlled by Arduino Uno + IoT Module (ESP8266/ESP32).
-
Maintains a temperature range ideal for insulin, vaccines, or samples.
-
Data is logged to the cloud (Blynk/ThingSpeak) with temperature graph and alerts.
💡 Key Features:
-
Rechargeable power system for portability.
-
Alerts (Email/SMS/App) when temperature goes out of range.
-
Great for field medical workers or mobile clinics.
