Dragino LMS01 LoRaWAN Wireless Leaf Moisture Sensor
The Dragino LMS01-LB/LS is a LoRaWAN 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-LB/LS 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.
The LoRa wireless technology used in LMS01-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
LMS01-LB/LS Supports BLE configure and wireless OTA update which make user easy to use.
LMS01-LB/LS is powered by 8500mAh Li-SOCI2 battery or solar powered + Li-ion battery it is designed for long term use up to 5 years.
