WT101(4 Digital Input Data Collection Node)
Introduction
Wireless Node WT101 has 4 digital input channel. It works with LoRa
Gateway BL280, supporting wet contact and dry contact(default is wet
contact). Collected data is sent to BL280 automatically.
It can be used in various industrial automation monitoring system.
Product Features:
Private LoRa communication protocol for simple, safe and reliable
connection
Parameters can be set in BL280 configuration software
Unique physical address to be identified from other nodes easily
Smart transmitting mechanism to auto adjust next transmission
according to node number once it’s configured with Gateway
Automatic re-connecting to gateway once it’s offline to prevent Open
