PCBA  Applications

• Automated Door Control: The PCBA precisely controls a motorized door mechanism, opening at sunrise and closing at sunset based on programmed timers or light sensor data to protect poultry from predators overnight.

• Scheduled Feeding Systems: It operates automated feeders by activating dispensing mechanisms at preset intervals, ensuring consistent food supply and portion control while reducing manual labor requirements.

• Environmental Monitoring: The board processes data from temperature and humidity sensors, enabling automatic climate control through ventilation fans or heating elements to maintain optimal coop conditions.

• Egg Collection Automation: In advanced systems, the PCBA controls conveyor belts or collection mechanisms that gently transport eggs from nesting boxes to storage areas, minimizing breakage and contamination.

• Water Management: It monitors water levels and controls valves or pumps to maintain clean water supply, with some systems incorporating automatic flushing and refilling cycles.

• Security and Predator Detection: The PCBA processes input from motion sensors and cameras, triggering alarm notifications or deterrent devices when potential threats are detected near the coop.

• Remote Monitoring and Control: Through connectivity modules, the PCBA enables farmers to monitor coop conditions and control automated features via mobile apps from any location.

• Data Logging and Analytics: The system collects and stores historical data on temperature patterns, feed consumption, and bird activity, helping optimize operations through trend analysis.

PCBA Features 

1. Motor Driver Circuits: The PCBA incorporates robust motor drivers capable of handling the current requirements for door mechanisms, conveyor systems, and ventilation fans with precise positional control.

2. Environmental Sensor Interfaces: It includes multiple sensor input channels for connecting temperature, humidity, ammonia gas, and light level sensors with appropriate signal conditioning circuitry.

3. Wireless Connectivity Modules: The board integrates Wi-Fi or LoRa modules for remote access, along with backup cellular connectivity options for locations without reliable internet service.

4. Power Management System: Employing sophisticated PMIC with battery backup support, the PCBA efficiently manages power distribution between motors, sensors, and control circuits, with solar charging capability for off-grid operation.

5. Real-Time Clock (RTC) Circuitry: Includes precision RTC components with battery backup to maintain accurate timekeeping for scheduling door operations and feeding cycles during power outages.

6. Protection Circuits: Features surge protection, overcurrent protection, and EMI filtering to ensure reliable operation in harsh agricultural environments with fluctuating power conditions.

7. Input/Output Expansion Capability: Provides GPIO headers and communication ports (UART, I2C, SPI) for connecting additional sensors, actuators, and peripheral devices as needed.

8. Robust Enclosure and Connectors: The PCBA is designed with conformal coating and utilizes waterproof connectors to withstand the humid, dusty, and corrosive environment typical of poultry farming operations.
