LLMS01 LoRaWAN Leaf Moisture Sensor 868MHz

The Dragino LLMS01 is a LoRaWAN leaf moisture sensor for IoT in agriculture. It is designed to measure leaf moisture and temperature and send it via LoRaWAN. The LLMS01 measures leaf moisture and temperature using the FDR method. It records the dielectric constant caused by the liquid on the leaf surface and converts this value into leaf moisture. The probe is shaped like a leaf to best simulate the characteristics of a real leaf. The probe has a density of 15 leaf vein lines per centimeter, allowing it to capture small droplets and achieve higher accuracy. Applications areas include sensor network applications such as irrigation systems, smart metering, smart cities, temperature measurements, etc. The LLMS01 is powered by an 8500mAh Li-SOCI2 battery, designed for long-term use for up to 5 years. Each LLMS01 comes pre-loaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the LLMS01 automatically connects when powered up and network coverage is available.
