1.1	22
39.6	23
75.2	24	The Dragino SPH01-LB/LS 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	25
75.2	26	SPH01-LB/LS 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/LS probe can be buried into soil for long time use.
1.1	27
75.2	28	The LoRa wireless technology used in SPH01-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.

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/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
