A detector model in AWS IoT Events contains expressions written in the AWS IoT Events expression language. An expression can have one of four primitive data types: integer, string, decimal, or Boolean. By checking your expressions for correct use of data types, you can be confident that your detector model will work as you expect. In this post, we describe the consequences of using wrong data types in your AWS ... Read More

Add to that polluted outdoor air making its way into our homes through ventilation, and you’ve got a cocktail of toxins floating around between your four walls. Clean air has proven positive health benefits. It can provide asthma and allergy relief, prevent sickness from bacteria and viruses, and help us sleep better which in turn boosts our immune system. Clean air even makes us smarter according to research. Blueair (a ... Read More

From healthcare to industrial, and from entertainment to retail, customers are looking for modern and scalable IoT solutions to make practical business decisions. For example, many exhibitions in public art museums employ an open-ended approach, where there is no clear starting or finishing point to the exhibition. The layout of an exhibition needs to take into consideration the way in which the viewers find their way through the exhibition contributes to the viewers’ engagement with the ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Ryan Dsouza. Industrial digital transformation is driving changes to the Operational Technology (OT) landscape, making it more connected to the internet, and, as a result, IT systems and solutions. Operational Technology is the use of hardware and software to monitor and control physical assets and production operation. Industrial control systems (ICS), an element of OT, is a general term that encompasses several types of control systems and associated instrumentation used for industrial process control. As these environments continue to evolve, OT environments are leveraging more IT solutions to improve ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Roy Kincaid. AWS recently announced the general availability of MQTT retained messages for AWS IoT Core. This feature allows you to store a single message per a given MQTT topic for delivery to any current and future topic subscribers. Creating a retained message simply requires setting a retained flag when publishing to let the AWS IoT Core broker know to save it. At that point the message is delivered to all current subscribers as normal, and also any new devices that subscribe to that topic in the future. Also ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Syed Rehan. As an IoT solution architect, customers often ask me how they can connect to AWS IoT Core (cloud) using a microcontroller unit (MCU). One solution is to use Bluetooth Low Energy (BLE) as the connection from the MCU to a mobile device; from there, the mobile device connects to the cloud. BLE works for consumer IoT device use cases such as thermostats, door locks, connected bicycles, smart watches, and many others. In this blog, I demonstrate how to use a Nordic nRF52840-DK board (MCU) to connect to ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Vishal Gupta. AWS IoT Core lets you securely ingest payloads from IoT devices to the AWS Cloud at a large scale—supporting billions of devices and trillions of messages. It also lets you process the messages and manage the devices from the cloud reliably and securely. One challenge you may have faced while designing your solution with AWS IoT Core is that there is a hard limit on maximum permissible size of MQTT payload. At the time of writing the blog, the maximum MQTT payload which AWS IoT Core can ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Jérôme Gras. I live in Toulouse, in the south of France, where the climate is classified as humid subtropical climate (Cfa in the Köppen climate classification). This is why swimming pools are so common here! My household is no exception. But as a geek, I also wanted to monitor the temperature of my swimming pool, consult real-time indicators, and view history. Let’s have a deep dive (pun intended) together: in this blog post, I demonstrate how to put AWS services together to cost-effectively build a water temperature monitoring solution ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: David Johnsen. Customer IoT applications require rapid over the air (OTA) updates to maintain the state of their IoT things. This becomes increasingly important as IoT fleets grow. Jobs for AWS IoT Device Management is a feature to push updates to targeted edge devices. Each job targets devices in static or dynamic AWS IoT thing groups. Static thing groups include a set of specified IoT things while dynamic thing groups contain things that match a specified query and automatically update if things are added that match this query. This ... Read More
