Product Description:

The ComWinTop 7-in-1 Soil Sensor is a comprehensive solution for monitoring soil conditions. This low-consumption sensor measures soil moisture, temperature, humidity, electrical conductivity (EC), pH, and NPK (nitrogen, phosphorus, potassium). Available with WiFi or 4G data logging, it features a built-in 128MB memory for storing data. The sensor's 4G module supports TCP/IP communication and data uploading to the CWT cloud platform, allowing for remote monitoring via website and app. Powered by an 8000mAh rechargeable lithium battery, it can operate for up to 1 year on a single charge (data sent every 30 minutes). Solar charging and IP68 protection ensure reliable outdoor performance.

Key Features:

• 7-in-1 Measurement: Soil moisture, temperature, humidity, EC, pH, NPK.
• WiFi or 4G Data Logging: Remote data access and monitoring.
• 128MB Data Storage: Large capacity for data logging.
• Adjustable Logging Interval: 1 minute to 24 hours.
• 4G Communication: TCP/IP, static IP/domain, CwtIO protocol.
• Adjustable Upload Interval: 1 minute to 24 hours.
• Low Power Consumption: Extended battery life.
• 8000mAh Battery: Built-in rechargeable lithium battery.
• Solar Charging Support: Direct solar panel connection.
• IP68 Protection: Water and dustproof for outdoor use.
• CWT Cloud Platform: Free cloud service for data viewing and export.

Important Notes:

• NPK Measurement Accuracy: The NPK measurement uses a rapid detection method with potential errors. Use with caution for planting reference.
