Manually preparing devices to connect to AWS IoT Core can be cumbersome, especially in large numbers. We present a script to help you prepare devices fast and reliably while storing certificates in the SPIFFS partition.
Elixir Phoenix is one of the best choices out there for building server side web applications. So, how does one build progressive web apps on it?
Designing a 'smart' product should also include the vision of fast firmware uploading, configuring device with the cloud securely and automation to meet demands and keep important data pouring seamlessly into the cloud.
A simple pre-thought out plan to include this feature could save you huge hassles of re-deployment of your ESP32-enabled WiFi connected devices in the long run.
Having shipped over 50000 ESP32 powered IoT devices, we have distilled our learnings into easy to use open source building blocks.
We integrate AWS IoT with the brand new AWS managed Grafana, compare it with ODFE and make a recommendation.
There are multiple RFID standards. we present a few simple rules to choose the right one for your application.
IoT devices can generate a lot of data, and of course there is a natural interest to apply machine learning techniques to look for trends and patterns. Of course, we have plenty of tools up in the cloud, and it is certainly possible to build a solution this way for some use cases.
Among the numerous applications that IoT technology has been applied to, there is a large class of applications that need some unique capabilities from their underlying hardware platform in order to enable their construction.
Among the more critical building blocks of an IoT solution, and one which should be thought about sooner than later is the concept of over-the-air (OTA) updates to your deployed fleet of devices.
Real time anomaly detection is now part of ODFE and allows applications such as predictive maintenance.
Contex makes creating server side plots easy with Elixir but the documentation could be better.
AWS IoT and ElasticSearch with Kibana is a classic combination for quick, scalable visualisations, analytics and alerts. This stack has only gotten better in 2020.
AWS IoT and aligned PaaS offerings have come a long way since being launched in the early 2010s. They allow you to build robust, scalable workflows for cloud-connected IoT applications.
Websockets are a communication protocol that allow the creation of persistent, bidirectional communication channels between client and server.
It all arises because of the dependence of the vast majority of IoT solutions on a cloud back-end.
No, not those X-Files. I am talking about those interesting measurement stories where we were, like Mulder and Scully desperately seeking a solution to a complicated problem.back-end.
When you are building IoT systems, one of the more difficult (and not yet satisfactorily solved) problems is the establishment of the semantics of a measurement that an IoT device reports up the food chain.
This is a picture of a simple lemon that I bought in the grocery store the other day. This particular brand of lemon is really juicy. It’s also an organic lemon which is important if you are going to use some of the rind for zest in your salad dressing recipe.
