Soil moisture meter

MicroLog V3ASoil moisture meter

MicroLog V3ASoil moisture meterIt is a system composed of MicroLog V3A data logger and SM 100 soil moisture sensor, designed for long-term and accurate measurement of soil moisture content.

The MicroLog V3A data logger is a small, three channel universal waterproof data logger with the following features: three voltage input channels, supporting different levels of voltage excitation, and meeting various measurement needs. Equipped with a waterproof casing, suitable for long-term monitoring in harsh environments. Easy data access, data can be read through infrared without opening the casing. Low maintenance cost, simple and convenient installation and setup process. The logging capacity is large and can handle various monitoring tasks. Powered by durable batteries to ensure long-term stable operation. Support Mini32 software for convenient data management and analysis for users.
