Today we’re announcing three new accelerators are available:

• The Car Detector project lets you detect passing cars with a camera, and publish reports to the cloud via a cellular connection.
• The Cold Chain Monitor shows you how to monitor a medication, and send SMS messages for alert conditions, such as high temperature
• The Water Quality Monitor project helps you collect water quality metrics from various sensors, and upload them to the cloud at a configurable interval.

Check them out! And view the full list of Blues accelerators at blues.dev/accelerators.

Today we’re pleased to release Scoop, an accessory for Notecard designed to provide a backup power source that is more resilient than the traditionally used Lithium-Polymer Battery (LiPo).

Scoop features a 250 Farads 3.8V Lithium-Ion Capacitor (LIC), a special type of capacitor that operates in a wider range of temperatures than LiPos, has a lower self-discharge rate, and does not have the shipping restrictions familiar to anyone who has worked with Lithium-based batteries.

To learn more, read the full Scoop writeup on our developer blog, check out the Scoop in our store, or get the technical details in the Scoop datasheet.

Today we’re announcing five new fully documented reference applications:

• Greenhouse Monitor: Monitor ambient light, ambient temperature, soil moisture, and soil temperature within a greenhouse.
• Emergency Vehicle Lights Monitor: Monitor the activation of emergency vehicle lights and report vehicle location.
• Cellular Modbus Client: Send requests and receive responses from Modbus servers via cellular.
• Vending Machine Monitor: Monitor inventory and detect power failures in a vending machine.
• Heat Index Monitor: Monitor temperature, humidity, and heat index in an outdoor location.

Check them out, as well as the rest of our accelerators, and if you have any questions feel free to reach out in our forum.

Today we’re announcing a new Notehub route that makes getting your data to Slack a breeze.

The new Slack route allows you to connect to any Slack channel and app, and configure your routes to forward some or all of your events.

Try it out yourself by following our Configuring a Slack Route guide.

Notehub Connectivity Assurance automatically adds data to a Notecard SIM’s data plan when you’re running low on data.

Connectivity Assurance is enabled by default if the Notehub Billing Account associated with your Notecard has a payment method on file, but we now offer ways of controlling your Connectivity Assurance preferences within Notehub.

Learn more about how it works in Managing Connectivity Assurance.

Today we’re announcing two new accelerators are available:

• The Cellular-Connected Electronic Kiosk shows you how to use a Raspberry Pi, a Notecarrier-Pi, and a Notehub to remotely manage and update content on a kiosk—without having to rely on a connection to a facility Wi-Fi network.
• The Audio Classifier shows you how to recognize audio patterns using an off-the-shelf microphone, the Notecard, and on-device machine learning.

Check them out! And view the full list of Blues accelerators at blues.dev/accelerators.

Today we’re announcing a new C library for fetching Environment Variables: Notecard Environment Variable Manager.

The library offers functions for retrieving Environment Variables from Notehub, as well as “watch variables” that allow you to watch for variable updates at a configurable interval.

The Notecard Environment Variable Manager is open source and available on GitHub. Give it a shot and let us know what you think.

Today we released a Postman Collection that makes it easy to perform Notehub API requests.

The Collection allows you to easily authenticate, pick the request you’d like to use, and make the appropriate call with the click of a button.

To get started today check out our Postman Collection documentation on blues.dev.

A new version of note-arduino, our official library for interacting with the Notecard in Arduino projects, is now available.

The 1.4.0 release includes updated support for multi-threaded applications, and provides new sendRequestWithRetry and requestAndResponseWithRetry methods to overcome hardware race conditions on cold start.

Check out the full changelog in GitHub, and follow our installation instructions to start using the new version in your favorite editor.

A new developer release of the Notecard firmware, version 5.1.1, is now available. The release includes a number of new features, such as the ability to perform asynchronous web requests, a way to schedule host firmware updates and host restarts, and some improvements to the status messages from the hub.sync.status request.

And more! Check out the release’s full changelog for more details, and when you’re ready, install the update on your devices from Notehub.
