1.1	21
39.6	22
67.6	23	The Dragino SPH01-LB is a (% style="color:blue" %)LoRaWAN Soil pH Sensor(%%) for IoT of Agriculture. It is designed to measure the soil PH and soil temperature, so to send to the platform to analyze the soil acid or alkali level. The probe is IP68 waterproof.
1.1	24
67.6	25	SPH01-LB probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect(% style="color:blue" %) soil's pH (%%)with high accuracy and stable value. The SPH01-LB probe can be buried into soil for long time use.
1.1	26
67.6	27	The LoRa wireless technology used in SPH01-LB 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.
1.1	28
67.6	29	SPH01-LB (% style="color:blue" %)supports BLE configure(%%) and (% style="color:blue" %)wireless OTA update(%%) which make user easy to use.
1.1	30
67.6	31	SPH01-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
62.4	32
67.6	33	Each SPH01-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

67.10	174	The SPH01-LB is configured as (% style="color:#037691" %)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 press the button to activate the SPH01-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
