📡 Communication Methods

• 433M Wireless (Primary Channel): Forward Error Correction technology, actual BER 10⁻⁵~10⁻⁶, transmission range up to 1-2km in open areas.
• LoRa (Backup Channel): Mesh network communication, max transmission distance 5km (line-of-sight), ideal for areas without public network coverage.
• 4G (Cloud): Automatic data upload to cloud platform, supports real-time viewing and historical analysis.
• RS485 Wired: On-site debugging and local data acquisition using Modbus RTU protocol.

🔧 Installation Recommendations

• Install the weather station in an open, unobstructed area, at a distance of at least 2 times the building height from any structures.
• Wind speed and direction sensors should be installed 2-3 meters above ground level.
• Soil sensors must be inserted vertically into the soil to ensure full contact with the soil.
• The solar panel should face south (northern hemisphere) with a tilt angle of 30-45°.
• The rain gauge must be kept horizontal with no trees or buildings obstructing the surrounding area.

• Regularly clean the rain gauge bucket and temperature/humidity sensor vents to prevent foreign objects from affecting measurement accuracy.
• Avoid using in highly corrosive gas environments to prevent damage to sensor elements.
• The device contains a built-in lithium battery. Do not disassemble or dispose of in fire to avoid danger.
• If data anomalies occur, perform a self-diagnosis via RS485 interface or contact technical support.
• During thunderstorms, it is recommended to disconnect external power to avoid lightning damage.
• When not in use for extended periods, store the device in a dry, cool place and charge it every six months to maintain battery activity.

Issue	Possible Cause	Solution
No data upload	SIM card expired / Weak 4G signal / Power failure	Check SIM card balance, power cycle, check solar power system
Abnormal temp/humidity readings	Sensor probe contaminated / Poor ventilation	Clean the probe, ensure good ventilation
Zero rainfall reading	Bucket jammed / Loose wiring	Check if the bucket moves freely, check wiring connections
Large soil data deviation	Sensor not fully inserted / Poor soil compaction	Re-insert vertically and compact surrounding soil
Communication failure	433M/LoRa signal interference	Adjust antenna direction, reduce transmission distance
