25 The Dragino LLMS01 is a (% style="color:#4f81bd" %)**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.

29 LLMS01 detects leaf’s(% style="color:#4f81bd" %)** 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.

31
32 (((
33 The LoRa wireless technology used in LLMS01 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.

114 == 2.1 How it works ==
115
116 (((
117 The LLMS01 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LLMS01. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
118 )))
119
120 (((
121 In case you can’t set the OTAA keys in the LoRaWAN OTAA server, and you have to use the keys from the server, you can [[use AT Commands >>||anchor="H5.UseATCommand"]]to set the keys in the LLMS01.
