	17
	18
42.5	19	The Dragino PS-LB series sensors are (% style="color:blue" %)LoRaWAN Pressure Sensor(%%) for Internet of Things solution. PS-LB can measure Air, Water pressure and liquid level and upload the sensor data via wireless to LoRaWAN IoT server.
6.2	20
42.5	21	The PS-LB series sensors include (% style="color:blue" %)Thread Installation Type(%%) and (% style="color:blue" %)Immersion Type(%%), it supports different pressure range which can be used for different measurement requirement.
6.2	22
	23	The LoRa wireless technology used in PS-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.
	24
	25	PS-LB supports BLE configure and wireless OTA update which make user easy to use.
	26
42.5	27	PS-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
6.2	28
	29	Each PS-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.

To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and activate the PS-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

40.4	839	=== 4.3.1 Battery Note ===
6.2	840
	841
	842	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.
	843
	844
40.4	845	=== 4.3.2 Replace the battery ===
6.2	846
	847
40.4	848	You can change the battery in the PS-LB.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.
6.2	849
40.4	850	The default battery pack of PS-LB 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)
