PCBA Applications Smart Kitchen Inventory and Egg Stock Management: The PCBA enables real-time monitoring of egg quantities by
detecting the presence or absence of eggs in each of the 14
individual slots, transmitting this data wirelessly to inform users
of current stock levels via a smartphone application . Automated Freshness Tracking and Rotation Assistance: The PCBA processes time-stamped data for each egg placed in a
specific slot, calculates the age of each egg individually, and
triggers an adjacent LED indicator to visually identify the oldest
egg, guiding users to consume it first and reduce food waste . Low Stock Alert and Shopping List Automation: The system analyzes inventory depletion patterns and automatically
sends push notifications to the user's smartphone when egg supplies
are running low, facilitating timely replenishment and seamless
integration with grocery shopping routines . Spoilage Detection and Food Safety Notification: The PCBA tracks the duration each egg has been stored and alerts
users when eggs exceed a predefined freshness threshold,
identifying specific eggs that are no longer safe for consumption
to prevent foodborne illness . Usage Pattern Analytics and Consumption Insights: The collected data on egg usage frequency and replenishment cycles
can be analyzed to provide household consumption trends, helping
users optimize purchasing habits and reduce waste.
PCBA Features Individual Optical Sensor Matrix per Egg Cup: The PCBA integrates 14 discrete optical or infrared sensors, each
positioned at the bottom of an individual egg-shaped cavity. These
sensors detect light occlusion when an egg is present, enabling
per-egg presence detection and independent age tracking for each
storage position . Multi-Channel LED Indicator Driver Array: Incorporates driver circuitry for 14 individual LED indicators,
each co-located with its corresponding sensor. The PCBA controls
these LEDs independently to illuminate the specific cup containing
the oldest egg, providing intuitive, at-a-glance visual guidance
without requiring smartphone interaction . Integrated Wi-Fi Connectivity Module (Electric Imp): The board features an embedded Electric Imp Wi-Fi module, a
compact network connectivity solution that enables the Egg Minder
to communicate directly with cloud servers, synchronize egg
inventory data, and deliver real-time status updates to paired
mobile applications . Ambient Light Sensing and Fridge-Door Detection: Includes an auxiliary ambient light sensor that detects when the
refrigerator door is opened, allowing the PCBA to optimize power
consumption by activating sensor readings and LED indications only
when the user is likely to be interacting with the device . Low-Power Microcontroller with Real-Time Clock (RTC): Employs an ultra-low-power MCU that maintains per-egg timestamp
data and manages the timing logic for freshness calculations. It
coordinates sensor polling, LED activation, and periodic Wi-Fi data
transmission while preserving battery life during extended idle
periods. Battery Power Management and Cold-Temperature Regulation: Utilizes a power regulation circuit specifically designed to
operate reliably from two AA batteries in near-freezing
refrigerator environments (typically 0-4°C), maintaining stable
voltage output to all components despite cold-induced battery
capacity degradation . Compact Form Factor and Ergonomic Enclosure Integration: The PCBA is engineered to fit within the slim 370mm x 112mm
footprint of a standard refrigerator shelf egg tray, with component
placement and routing optimized to accommodate the 14 individual
sensor-LED pairs while maintaining low overall height.
