The Dragino LMS01-NB is a NB-IoT Leaf Moisture Sensor for IoT of Agriculture. It is designed to measure the leaf moisture and temperature, so to send to the platform to analyze the leaf status such as : watering, moisturizing, dew, frozen. The probe is IP67 waterproof.

LMS01-NB detects leaf's moisture and temperature use FDR method, it senses the dielectric constant cause by liquid over the leaf surface, and cover the value to leaf moisture. The probe is design in a leaf shape to best simulate the real leaf characterizes. The probe has as density as 15 leaf vein lines per centimeter which make it can senses small drop and more accuracy.

LMS01-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

LMS01-NB supports BLE configure and OTA update which make user easy to use.

LMS01-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

LMS01-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
