A couple of years ago the LoRaWAN Network became globally available!
Since then TheThingsNetwork.org has led the field in making this innovative technology available to both individuals and organisations.
Sensor tasks dictate the monitor size and can be as small as a coin.
Length and duration of transmissions dictate the battery life which can be up to about ten years!
Driven by batteries that transmit over great distances by "line-of-sight" and only slighlty hindered by solid obstacles. Radio transmissions are requires to conform rigidly to specifications.
Created to monitor and chart Sensors in various locations in England and soon to have a BangkoK Sensor connected to the local LoRaWAN Gateways.
