The Efento wireless soil moisture logger accurately measures soil water content and soil temperature. Ideal for agriculture, horticulture, irrigation management and soil research. Thanks to integration with the free Efento Android app, you can easily configure the device, read out measurement data, set alerts and generate automatic reports.

The logger is equipped with an external Watermark soil moisture probe (3 m) and a temperature probe (3 m) for accurate measurements in any soil condition. The robust IP67 housing protects the device against water and dust, ensuring reliable performance year after year.

With a battery life of up to 5 years, a memory capacity of 40,000 readings and a wireless range of up to 100 m (LOS), this is the ideal solution for long-term, low-maintenance monitoring.
