Store dust sensor data on nRF Connect for Cloud
In this example we are using the nRF Connect for Cloud Device API, which is a free service for protyping IoT products and is built on top of AWS IoT, to store dust sensor readings. The API is device-agnostic and can store data from any kind of device. In this example we use an Espruino Wifi (firmware version 2v01). The Espruino will connect to the AWS IoT MQTT broker using TLS, and regularly publish temperatore and…
