In this post, I’ll be providing a high level view of IoT data gathering, processing, and presentation. The post won’t contain exact details that may pertain to your needs, but this overview should cover most items to get started. This video demonstration steps through the process of setting up InfluxDB for use with Node-Red. It is followed up with another video that continues with Grafana integration with InfluxDB. I found these demonstrations to be concise and to the point. IoT…

This post will cover how to use the Sonoff RF Bridge hardware as a wifi scanner and display its results in Node Red. Here is a high level view of what will be covered. The hardware is an IoT device intended as a gateway between 433 Mhz sensors and a wifi network. That purpose will be abandoned. Instead the device will be modified to allow it to be programmed using a serial to usb converter. With that, firmware will be…

In the last post, I covered how to generate audio natively with the ESP8266 module.  The hardware to do this is rudimentary.  I demonstrated how to generate CW (Morse Code), DTMF, synthesized speech, and audio.  This post will expand on some of those concepts by decoding CW and DTMF signals.  The following Fritzing wiring diagram will be the foundation for all of the code covered in this post. The Encode Module will be the signal source for the Decoding modules. …
