We are looking for an experienced developer in electronic design, firmware, and system integration to create an autonomous surveillance system. The device will be solar-powered, capable of detecting motion, performing AI-based inferences, and sending alerts through configurable communication modules.
The system is intended for operation in remote areas with limited connectivity, optimizing energy consumption and offering flexible communication options (Wi-Fi, LoRaWAN, or 4G/LTE).
Project Objectives:
Design and develop a compact and autonomous solar-powered device.
Integrate motion detection capabilities using PIR sensors.
Incorporate image processing using the Coral Dev Board Micro to detect specific objects.
Implement a data transmission system configurable based on the installation environment (Wi-Fi, LoRaWAN, or 4G/LTE).
Optimize energy management to ensure continuous operation, even with limited sunlight.
Device Operations Flow:
Idle State:
Only PIR sensors remain active to detect motion.
All other system components (cameras, Coral, communication modules) remain off or in low-power mode.
Motion Detection:
A PIR sensor detects motion and sends a signal to the management microcontroller.
The microcontroller activates the corresponding camera and wakes up the Coral Dev Board Micro.
Image Capture and Processing:
The camera captures an image or sequence of images and sends it to the microcontroller.
The microcontroller transmits the data to the Coral for real-time inference.
Object Identification:
The Coral analyzes the images using AI models (TensorFlow Lite) to detect objects included in a predefined "blacklist."
Data Transmission:
If an object of interest is detected:
The microcontroller activates the configured communication module (Wi-Fi, LoRaWAN, or 4G/LTE).
Alerts and relevant data are sent to a preconfigured server or endpoint.
If no relevant objects are detected, the system returns to idle state.
Energy Management and Recovery:
The used components are turned off or placed into low-power mode.
The microcontroller monitors the batteries, switching between them as needed to ensure efficient charging.
The system resumes passive monitoring using the PIR sensors.
Key Features of the System:
Energy Management:
Solar panels (10-20W) with MPPT controller.
Three 12V, 10Ah LiFePO4 batteries with automatic rotation to maximize lifespan.
Voltage regulators to power components at 5V and 3.3V.
Motion Detection and Processing:
PIR sensors to trigger system activation.
OV2640 cameras controlled by microcontrollers (ESP32 or STM32) and managed using MOSFETs.
AI Processing:
Coral Dev Board Micro for real-time inferences.
Communication Modules:
Wi-Fi (ESP32), LoRaWAN (Heltec LoRa), or 4G/LTE (SIM7600), selectable based on site requirements.
System Monitoring and Management:
Secondary microcontroller for managing energy, environmental sensors (temperature and humidity), and communication modules.
Freelancer Responsibilities:
Design the system PCB considering a modular and energy-efficient architecture.
Develop firmware to manage motion detection, data processing, alert transmission, and system monitoring.
Perform hardware and firmware integration tests to ensure expected functionality.
Document the project, including diagrams, technical specifications, and user manuals.
Technical Requirements:
Experience designing PCBs using KiCad (or similar software).
Knowledge of programming microcontrollers (ESP32/STM32).
Experience with communication modules (Wi-Fi, LoRaWAN, 4G/LTE).
Familiarity with solar power systems and battery management.
Understanding of image processing with AI (TensorFlow Lite is a plus).
