Dragino LLMS01 LoRaWAN Leaf Moisture Sensor 868MHz

The Dragino LLMS01 is a LoRaWAN leaf moisture sensor designed for IoT applications in agriculture. It measures and transmits leaf moisture and temperature data over LoRaWAN. The sensor utilizes the FDR method to detect the dielectric constant caused by liquid on the leaf surface, converting this value into leaf moisture. The probe is shaped like a leaf to accurately simulate real leaf properties, featuring a density of 15 leaf vein lines per centimeter for detecting small droplets with higher accuracy.

Applications include sensor networks for irrigation systems, smart metering, smart cities, and temperature measurements. The LLMS01 is powered by an 8500mAh Li-SOCI2 battery, designed for long-term use of up to 5 years. Each unit comes preloaded with unique keys for LoRaWAN registration, allowing automatic connection to the local LoRaWAN server upon power-up if network coverage is available.
