Hardware, Embedded Systems, and IoT Projects

Collection of Hardware, Embedded Systems, and IoT Projects from Academic Problem-Based Learning (PBL) at IPB University.

📑 Featured Projects

Category: Analog Electronics
Key Hardware: Transformer 2A CT, Bridge Diode (1N4007), IC LM317 Regulator, 5kΩ Potentiometer
Summary: Designed and built a linear regulated DC power supply converting 220V AC into an adjustable 3V - 12V DC output, validated with Falstad/Tinkercad simulations and physical assembly in an enclosure.

Category: Digital Electronics & Microcontroller
Key Hardware: Arduino Uno, MLX90614 IR Temp Sensor, Pulse Sensor Amped, DFPlayer Mini MP3, LCD Display
Summary: Developed an interactive non-invasive health monitoring device that measures body temperature and pulse rate (BPM), classifies health conditions based on predefined thresholds, and provides real-time visual and voice responses.

Category: Sensor & IoT Systems
Key Hardware: MQ Gas Sensor, ESP Board, Buzzer, ,DC Motor, LCD Display
Key Software: Telegram bot chat, Adafruit IO
Summary: Developed an automated IoT laboratory safety system that monitors CO and Butane gas levels in real-time, triggering local physical responses (exhaust fan, buzzer, LED) and sending emergency alerts via Telegram and Adafruit IO.
