3.2	25	== 1.1 What is LoRaWAN Soil pH Sensor ==
2.2	26
3.2	27	The Dragino LSPH01 is a (% style="color:#4f81bd" %)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.
2.2	28
3.2	29	LSPH01 probe is made by Solid AgCl reference electrode and Pure metal pH sensitive electrode. It can detect soil's (% style="color:#4f81bd" %)pH (%%)with high accuracy and stable value. The LSPH01 probe can be buried into soil for long time use.
2.2	30
	31	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.
	32
3.2	33	LSPH01 is powered by (% style="color:#4f81bd" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
2.2	34
3.2	35	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.

2.2	939	The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.

2.2	946	You can change the battery in the LSPH01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
	947
	948	The default battery pack of LSPH01 includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)
