26 (((
27 The Dragino LSPH01 is a (% style="color:blue" %)**LoRaWAN Soil pH Sensor**(%%) for IoT of Agriculture. It is designed to measure the (% style="color:blue" %)**soil PH and soil temperature**(%%), so to send to the platform to analyze the soil acid or alkali level. The probe is IP68 waterproof.
28 )))
29
30 (((
31 LSPH01 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 LSPH01 probe can be buried into soil for long time use.
32 )))
33
34 (((
35 The LoRa wireless technology used in LSPH01 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.

42 (((
43 Each LSPH01 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.

106 (((
107 The LSPH01 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 LSPH01. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

111 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 LSPH01.
