1. Introduction
R718J is a ClassA external dry contact device based on LoRaWAN open protocol of Netvox. It can externally connect various
switches, buttons, relays and reed switch output. It can detect the closing or disconnecting signal of dry contact and is compatible
with LoRaWAN protocol.
LoRa wireless technology:
LoRa is a wireless communication technology dedicated to long-distance low-power consumption. Its spread-spectrum
modulation method greatly increases the communication distance compared with other communication methods, and can be
widely used in long-distance low-rate IoT wireless communication fields in various occasions. Such as automatic meter reading,
building automation equipment, wireless security systems, industrial monitoring and control. It has the characteristics of small
size, low power consumption, long transmission distance and strong anti-interference ability.
LoRaWAN:
LoRaWAN defines an end-to-end standard specification using LoRa technology to ensure interoperability between devices and
gateways from different vendors.
