DRAGINO LLMS01-EU868 leaf moisture sensor

overview

Dragino LLMS01 is a LoRaWAN leaf moisture sensor for IoT in agriculture. It is designed to measure leaf moisture and temperature and send to the platform to analyze leaf status, such as: watering, humidification, dew, frost. The probe is IP67 waterproof.

The LLMS01 measures leaf moisture and temperature using the FDR method. It detects 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, which allows it to detect small drops and higher accuracy.

The LoRa radio technology used in the LLMS01 enables the device to transmit data and reach extremely long ranges at low data rates. It provides extremely long range spread spectrum communication with high interference immunity while consuming minimal power.

The LLMS01 is powered by an 8500mAh Li-SOCI2 battery, which is designed for long-term use of up to 5 years.

Each LLMS01 is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the connection is established automatically after power-on.
