The Dragino LMS01-LS Leaf Moisture Sensor (3000mAh Li-Ion & Solar Panel / US915) 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, and freezing. Utilizing the Frequency Domain Reflectometry (FDR) method, the sensor detects moisture and temperature by assessing the dielectric constant changes caused by liquid on the leaf surface. The probe is meticulously designed in a leaf shape, featuring a density of 15 leaf vein lines per centimeter, ensuring precise detection of small moisture droplets.
This sensor employs LoRa wireless technology, which facilitates ultra-long-range communication with robust interference resistance and minimal power consumption. It supports Bluetooth Low Energy (BLE) configuration and 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. Pre-loaded with unique keys for LoRaWAN registration, the sensor automatically connects to a local LoRaWAN server upon activation.
The LMS01-LS features an IP67-rated waterproof probe, making it suitable for outdoor use in various weather conditions. It supports Bluetooth v5.1 and allows for remote configuration via LoRaWAN, making it an ideal choice for smart agriculture applications.
