The Dragino LMS01-LS Leaf Moisture Sensor (3000mAh Li-Ion & Solar Panel / EU868) is an advanced IoT device tailored for agricultural applications. It is engineered to measure leaf moisture and temperature, providing insights into various leaf conditions such as watering, moisturizing, dew formation, and freezing. The sensor employs the Frequency Domain Reflectometry (FDR) method to detect moisture and temperature by assessing the dielectric constant changes due to liquid presence on the leaf surface. Its probe is meticulously designed in a leaf shape, featuring a density of 15 leaf vein lines per centimeter, ensuring precise detection of even small moisture droplets.
This sensor utilizes LoRa wireless technology, which facilitates ultra-long-range communication with robust interference resistance and minimal power consumption. It is equipped with Bluetooth v5.1 for configuration and supports wireless Over-The-Air (OTA) updates, enhancing user convenience. The device is powered by a solar panel in conjunction with a 3000mAh Li-ion battery, enabling it to function efficiently for up to five years. Upon activation, it automatically connects to a local LoRaWAN server, thanks to its pre-loaded unique keys for LoRaWAN registration.
The Dragino LMS01-LS supports LoRaWAN 1.0.3 Class A and is designed to monitor not only leaf moisture and temperature but also the battery level. It features an IP66-rated waterproof enclosure and an IP67-rated sensor probe, ensuring durability and reliability in various environmental conditions. This sensor is particularly beneficial for smart agriculture, offering a sophisticated solution for monitoring and managing crop health and irrigation needs.
