#Problem

Modern homes require both comfort and safety, but many indoor environmental changes still need to be handled manually. A sudden drop in temperature or low humidity can reduce comfort and affect health, while smoke, gas leakage, or early fire conditions can quickly become dangerous if they are not detected in time. Existing household devices often work independently and lack coordinated automatic response. Some smart home systems also rely on network connectivity or pre-built software platforms, which may reduce reliability when fast local action is needed.

#Solution Overview

We will design a compact embedded hardware system that monitors key indoor environmental conditions and responds automatically through local control. The system will be based on an STM32 microcontroller and will focus on real-time sensing, local decision making, and coordinated actuation without relying on existing smart home software platforms.

Our design will monitor temperature, humidity, smoke, and gas-related hazards. Based on these conditions, the system will regulate the environment or issue warnings through hardware responses such as ventilation, heating, humidification, and alarms. The final prototype will prioritize functional integration, compact size, and reliable demonstration rather than furniture-like appearance.

#Solution Components
Environmental Sensing Module

This module measures temperature, humidity, smoke concentration, and combustible gas indicators. It provides real-time environmental data for system monitoring and hazard detection.

#Embedded Control Module

This module uses an STM32 microcontroller as the core of the system. It collects sensor data, determines system state, and coordinates local responses based on predefined control logic.

#Response and Actuation Module

This module performs the physical response of the system. It can activate devices such as a ventilation fan, heating element, humidification unit, buzzer, or warning lights according to the detected condition.

#User Interface Module

This module displays system status and supports simple user interaction. It may include a small display, indicator lights, and control buttons for observing readings and warning states during demonstration.

#Criteria of Success

Our product should be able to continuously monitor major indoor environmental conditions and detect abnormal situations in real time. The system should automatically trigger the proper local hardware response when temperature, humidity, smoke, or gas conditions move beyond acceptable ranges. In hazardous situations, the prototype should prioritize warning and protective actions such as alarms and ventilation. The final system should operate as a compact and integrated hardware prototype with coordinated sensing, control, response, and user feedback.

Bone Conduction Lock

Featured Project

A lock that is unlocked using vibrations conducted through the bones in the user’s hand. The user wears a wristband containing a haptic motor. The haptic motor generates a vibration signal that acts as the "key" to the lock. When the user touches their finger to the lock, the signal is transmitted through the user’s hand and is received at the lock. If the lock receives the correct "key", then it unlocks.
