1. Introduction
R313LA is a Wireless Infrared Proximity Sensor for Netvox ClassA type devices based on the LoRaWAN open protocol.
It has an infrared proximity sensor that can detect if there is object (toilet paper) existing within its detection range and transmits the
detected data to gateway for display via a wireless network.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other
communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely
used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation equipment,
wireless security systems, industrial monitoring. Main features include small size, low power consumption, transmission distance,
anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways
from different manufacturers.
