Case Details
Core Advantages & Scenario Adaptation
Environmental Adaptability
- Wide Temperature Operation (-40°C ~ 85°C): Suitable for extreme field environments (greenhouses/cold regions).
- IP30 Protection + Vibration Resistance (2g acceleration tested): Withstands vibrations from agricultural machinery and dust.
- EMC Level-3 Protection (EFT±4kV, ESD±8kV): Resists electrical interference in farm environments (e.g., irrigation pump switching).
Flexible I/O Expansion
Sensor Integration:
- Soil temperature/humidity, light intensity → Y33/Y34 (4AI single-ended/differential 0~10V).
- pH/EC monitoring → Y36 (differential ±10V high-precision acquisition).
- Weather station data (wind/rainfall) → Y13 (dry contact DI) or Y95 (pulse counting).
Actuator Control:
- Irrigation solenoid valves → Y24 (relay output) or Y22 (NPN DO).
- Fertilizer spreader speed control → Y95/Y96 (PWM output for motor speed).
Edge AI & Data Processing
6TOPS NPU enables real-time field analysis:
- Crop disease/pest identification (TensorFlow model deployment).
- Drone image processing (4K@60fps H.265 decoding + OpenCV).
Multi-core Architecture (A72+A53+M0):
- A72 runs AI algorithms; M0 core handles real-time control (e.g., precision irrigation timing).
Communication & Cloud Connectivity
- 4G/5G Module (Mini PCIe slot) → Remote data transmission in network-limited areas.
- Dual Gigabit Ethernet → Connects to local LoRa gateways or machinery CAN bus.
BLIoTLink Protocol Software:
- Direct integration with agricultural cloud platforms (e.g., Alibaba Cloud IoT, ThingsBoard), supporting Modbus-to-MQTT soil data uploads.

- Linux-RT kernel → Guarantees real-time irrigation control (<100μs response).
Development Tools:
- Node-RED: Drag-and-drop automation logic (e.g., humidity <30% → trigger irrigation).
- Qt Examples: Custom HMI interfaces for machinery, displaying field maps/sensor heatmaps.
Cloud Integration:
- BLIoTLink pushes sensor data to cloud platforms to generate fertilization/irrigation optimization strategies.
- BLRAT Remote Tool: Online debugging reduces field maintenance costs.
Risk Mitigation
-
Power Stability: Use wide-voltage input (9-36V DC) with overcurrent protection for volatile farm grids.
-
Moisture Protection: Despite passing humidity tests, seal interface ports (e.g., RS485 terminals).
-
Expandability: Reserve Y-slots for future sensors (e.g., Y58 for CO₂ monitoring).
Note: For large farms, deploy multiple BL440 units networked via HDMI2.1 multi-screen monitoring. Integrate with ROS for coordinated agricultural robotics.
