LoRaWAN leaf moisture sensor Dragino LMS01-LB

LMS01-LB — is a LoRaWAN leaf moisture sensor for the Internet of Things in Agriculture. It is designed to measure humidity and leaf temperature , to send to the platform to analyze the state of the leaves, for example: watering, moistening, dew, frozen. The probe is waterproof according to the IP67 standard.

LMS01-LB detects humidity and temperature leaves using the FDR method, it senses the dielectric constant caused by liquid on the leaf surface and overlays the leaf moisture value. The sensor is designed in the shape of a leaf to best mimic real leaf characteristics. The probe has a density of 15 lines of leaf veins per centimeter, thanks to which it can sense small drops and more accurately.

The LoRa wireless technology used in the LMS01-LB allows the device to send data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.

LMS01-LB Supports BLE configuration and wireless OTA update , which makes it easy for the user to use.

LMS01-LB is powered by Li-SOCI2 battery with a capacity of 8500 mAh , designed for long-term use up to 5 years.

Each LMS01-LB is pre-loaded with a set of unique LoRaWAN registration keys, register these keys to the local LoRaWAN server and it will connect automatically after power on.
