Widespread availability of LoRaWAN wireless sensors is finding many applications due to their low installation costs.
However, especially in rural areas or in communication blind spots, previous LoRaWAN solutions can be unsuitable. LoRaWAN architecture relies on uploading all node data through a gateway, to a cloud database for processing and data logging-Control actions require a separate executive running elsewhere. While a local wireless network can reliably connect clusters of sensor nodes to the gateway, it may not be able to transmit this data to the cloud 100% of the time. Loss of communications creates intermittent functionality, undesirable where the application requires control actions based on the sensor data.
Following from years of expertise in reliable data collection from remote places around the world, Dexdyne has successfully created an IP65-rated autonomous wireless Edge controller/data logger using the LoRaWAN IoT network, namely DXP400-LGW.
This new product overcomes the difficulties outlined above, by removing the reliance on continuous cloud connectivity for the successful use of LoRaWAN solutions on the ground. Our product successfully decodes and logs the incoming LoRaWAN payloads, and takes the necessary actions locally on site.
The Edge device is well suited as an autonomous wireless controller in applications such as smart agriculture, monitoring and control of odour, landfill bore-holes, air quality and many others. Because it has local data logging and executive ability, it will continue to log and control without continuous cloud connectivity.
This architecture:
Creates a more reliable system by removing one link in the chain for simple data logging.
Improves latency between the receipt of monitored data and the desired control response.
Offers lower operational costs because data uploads are filtered and do not need to be as frequent. This reduction in volume and frequency makes the use of expensive satellite links more viable.
Can also integrate data from Modbus-enabled devices and works seamlessly with our Cloud-based, user-friendly web-dashboard which provides a highly integrated, enterprise level, IoT solution.
