The Dragino LMS01-LB Leaf Moisture Sensor (8500mAh Li/SOCl2 / US915) is an advanced IoT device designed for agricultural applications. It specializes in measuring leaf moisture and temperature, providing critical data for analyzing leaf conditions such as watering needs, moisture levels, dew presence, and potential freezing. The sensor employs the Frequency Domain Reflectometry (FDR) method to detect the dielectric constant caused by liquid on the leaf surface, converting this data into precise moisture readings. Its probe is crafted in a leaf shape with a density of 15 vein lines per centimeter, enhancing its ability to detect small moisture droplets with high accuracy.
The device utilizes LoRaWAN wireless technology, enabling it to transmit data over long distances with low data rates, ensuring robust communication with high interference immunity while maintaining minimal power consumption. It supports Bluetooth configuration and wireless over-the-air updates, facilitating ease of use and adaptability. The sensor is powered by an 8500mAh Li-SOCI2 battery, designed for long-term operation of up to five years, and can also be solar-powered with a Li-ion battery.
Each unit is pre-loaded with unique keys for seamless LoRaWAN registration, allowing automatic connection to a local server upon activation. The sensor's probe is IP67 rated for waterproofing, ensuring durability and reliability in various environmental conditions. This makes it an ideal solution for smart agriculture, providing essential insights into plant health and optimizing resource management.
