Over the river and through the woods...

We've deployed a few (six at the moment) LoRaWAN temperature and humidity sensors around our house and apartment.

These sensors 'ping' local LoRaWAN gateways using the LoRaWAN protocol. The gateways are actually Helium Hotspots.

The gateways send data to the Helium cloud via Wi-Fi and the public Internet. The Helium cloud triggers a call to a webhook which is a Lambda function running in AWS. The Lambda writes the temperature and humidity readings into a DynamoDB table.

Tihs diagram, from a bootcamp back in 2018, shows an overall deployment similar to ours. In our case, the end nodes are the sensors. The gateways are Helium Hotspots. The network server is the Helium cloud. From a LoRa perspective, AWS is an application server, on the right.

I used SvelteKit to build this web 'app'. It calls an API implemented in AWS. The API gets data from the table and ths app displays it.
