7-in-1 Smart Soil Sensor with WiFi/4G Data Logger – Moisture, Temperature, EC, pH & NPK Monitor with Built-In Battery

Take the guesswork out of soil management with the 7-in-1 Soil Moisture, Temperature, EC, pH, and NPK Sensor with WiFi or 4G Data Logger. Designed for farmers, greenhouse operators, agricultural researchers, landscapers, and smart farming enthusiasts, this advanced soil tester delivers real-time monitoring of critical soil conditions to help optimize crop growth and improve yields.

This intelligent soil monitoring system measures soil moisture, temperature, electrical conductivity (EC), pH, nitrogen (N), phosphorus (P), and potassium (K) in a single compact device. Whether you're managing a commercial farm, greenhouse, orchard, garden, or research project, this sensor provides valuable insights into soil health and environmental conditions.

Featuring low-power technology and a built-in rechargeable lithium battery, the sensor can operate for up to one year on a single charge when transmitting data every 30 minutes. For remote deployments, the integrated solar charging circuit allows direct connection to a solar panel, providing long-term autonomous operation without requiring a separate solar charge controller.

Choose between WiFi connectivity for local network access or 4G communication for remote monitoring. The industrial-grade 4G module supports multiple regional frequency bands, making it suitable for deployment across North America, Europe, Australia, Asia, Africa, and other global markets. Data is transmitted securely using the CwtIO communication protocol and can be uploaded at customizable intervals ranging from one minute to twenty-four hours.

The built-in 128MB memory provides extensive data logging capacity, allowing users to store historical measurements and track soil trends over time. Real-time and historical data can be viewed through the free CWT Cloud platform, accessible from both web browsers and mobile applications. Users can also export data logs for analysis, reporting, and research purposes.

Built for harsh outdoor environments, the sensor features a rugged IP68 waterproof and dustproof enclosure, ensuring reliable performance in rain, irrigation systems, and challenging agricultural conditions. Fast response times and high-accuracy measurements provide dependable monitoring of changing soil conditions.
