The N331 Zigbee Soil Sensor provides real-time monitoring of soil temperature and humidity, ensuring optimal plant conditions. With accurate measurements, customizable alerts, and seamless integration with Zigbee systems, it supports smart automation for irrigation and more. Requires a Zigbee Gateway (sold separately).

🌱 2-IN-1: The N331 Zigbee Soil Sensor offers precise and real-time monitoring of both soil temperature and humidity, providing a comprehensive overview of your plant's environment. It accurately measures soil moisture from 0-100% RH and temperature from 0-85°C, with a humidity accuracy of ±1% and a temperature accuracy of ±0.5°C. This 2-in-1 sensor ensures your plants are always in optimal conditions, promoting healthier growth and better yield.

🌱 Long Battery Life: Powered by 4 AA alkaline batteries (NOT included), the sensor boasts a long battery life of 6 months to 1 year, ensuring reliable performance over time. Installation is simple; just connect the sensor to a Zigbee gateway (sold separately) for seamless integration into your smart home ecosystem. This ease of setup makes it ideal for gardeners and farmers looking for a hassle-free monitoring solution.

🌱 Clear Data Display: The app features a user-friendly interface with clear and intuitive data visualization. Real-time temperature and humidity data are displayed at the top of the interface (updated every 30 seconds), while bar charts provide a detailed view of historical data with multiple modes:
     - Hour Mode: Displays the daily average value, with bar charts showing hourly averages;
     - Day Mode: Displays the average values for the past 30 days, with bar charts showing daily averages;
     - Month Mode: Displays the average values for the past 12 months, with bar charts showing monthly averages.
The historical data can be exported via the 'Export' button, making it easy for analysis and record-keeping.

🌱 Smart Scene Linkage: The device supports multiple intelligent linkage scenarios for collaborative operation:
    - Automatically water or stop watering by linking with a smart irrigation timer based on soil humidity or temperature conditions;
    - Execute commands based on local disaster warnings;
    - Customize activation conditions (e.g., status or time periods) to optimize scene-triggering efficiency;
    - Additional diverse smart linkage functions to meet the needs of agricultural planting and smart home management.

🌱 Wide Application Scenarios: The sensor allows for device sharing with family members, making collaborative management convenient. Leveraging Zigbee technology, the data upload rate reaches up to 250kbps, and soil temperature and humidity data are regularly transmitted to the mobile app or cloud. It is widely applicable to agricultural planting, gardening management, and greenhouse control, providing users with a scientific and reliable solution for environmental monitoring and management.

⚠ Note:
1. Zigbee Gateway Required:
Please note that this product does not include the Zigbee Gateway. The N331 Zigbee Soil Sensor requires a Zigbee Gateway to function properly. The Zigbee Gateway must be purchased separately. Without the gateway, the sensor will not work.
2. Battery Replacement:
Avoid replacing the battery in rainy conditions to prevent rainwater from entering the device. Moisture inside the shell may damage the internal components.
3. Proper Sensor Placement:
When using the device, ensure the sensor is fully inserted into the soil until it reaches the bottom for accurate measurements.
4. Sealing Ring Usage:
Always reinstall the sealing ring correctly after replacing the battery. Failure to do so may weaken the waterproof performance.
5. Avoid Damage to the Sensing Plate:
Do not rub the sensing plate against the ground to prevent damage to the circuit board.
6. Data Refresh:
The Zigbee sensor refreshes temperature and humidity data every 30 seconds by default.
If immediate data refresh is needed, press the configuration button on the device to update the sensing data instantly.
