22 == 1.1 What is LoRaWAN Load Cell Converter ==
23
24
25 Dragino LCC01-LB is a (% style="color:blue" %)**LoRaWAN Load Cell Converter**(%%) for IoT solutions. It is used to accurately (% style="color:blue" %)**measure the weight of objects**(%%) and then upload it to the IoT server through the LoRaWAN wireless protocol.
26
27 The LCC01-LB has a (% style="color:blue" %)**standard 4-wire interface**(%%) which can connect to different type of load cell. It supports (% style="color:blue" %)**different scaling from gram to ton**.
28
29 With LCC01-LB and a suitable load cell, user can build up a weight measurement loT solution. Applications are suitable for such as: truck scales, railway scales, supermarketscales, bench scales, heavy duty scales or any type of standard scale.
30
31 The LoRa wireless technology used in the LCC01-LB allows the device to send data at low data rates and reach extremely long distances. It provides ultra-long-distance spread spectrum communications and high interference immunity while minimizing current consumption.
32
33 LCC01-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
34
35 LCC01-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%) , which can last up to 5 years of long-term use.
36
37 Each LCC01-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to LoRaWAN server and it will auto connect after power on.

254 (% style="color:blue" %)**Step2:**(%%) Determine Scale Factor
255
256 Enter Scale Factor according to requirements. The weight reading range is 0~~65535(g). If user want to Calibate to a high scale for example 1T, he should set the scale factory.
257
258 For example,
259
260 * If the load cell range is 0~~50kg, Use 1 as scale factor
261 * If the load cell range is 0~~500kg, use 10 as scale factor. the reading range = Weight Reading x Scale Factor = 0 ~~ 655350g (655.35kg)

290
291 The LCC01-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 LCC01-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

639 If a negative number appears, it may be that the 0 point has not been calibrated properly. Just follow the calibration process again.
640
641 If after recalibration, after placing the object, it was originally 100, but the result shows -100, this situation is caused by the sensor signal line being connected incorrectly, or the pressure sensor being installed incorrectly.
