Note:
①
lower case letter x is node ID, for example “TEMPx” means TEMP1. It’s the temperature of
node with ID 1
②
Node power voltage only exists in node WT103, WT104, WT105 and WT106

Different nodes collect different data. Details can be viewed from
13 Appendix D LoRa Node Introduction
WT100 (RS485 Transparent Transmission Node)
Introduction:
Micropower W
ireless LoRa Node WT100 is serial port
transparent transmission module. It’s based on LoRa spread
spectrum modulating technology with half-duplex
communication. It has MCU with receiving-transmission
program for transparent data transmission. Users don’t need to
do programming. It can be used easily on the site without
configuration.
Remote transmission node WT100 can connect RS485 devices
or sensors to Gateway BL280 and cloud to collect data from
cloud. Multiple Multiple WT100s can form a group network.
Master will collect data from other WT100.
