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 them over LoRaWAN. The LLMS01 measures leaf moisture and temperature using the FDR method. It captures the dielectric constant caused by the liquid on the leaf surface and converts the 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 drops and achieve higher accuracy. Applications 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 of up to 5 years. Each LLMS01 comes preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the LLMS01 will automatically connect when powered on, provided there is network coverage.
