How to Use Particle's Powerful Bluetooth API

I was defeated. I had spent the whole night trying to get a Bluetooth Low Energy project working. It was painful. It was frustrating. I was ready to give up. That was during the early days of Bluetooth Low Energy. Since then it’s gotten easier and easier to develop. The Particle Mesh Bluetooth Library is no exception. It’s powerfully simple to use. So much so that you’ll have a device with BLE before you can say “Particle has Bluetooth....

How to Define a Protocol Buffer Bluetooth Low Energy Service: Part 3

In Part 1 we’ve learned the anatomy of a Protocol Buffer. In Part 2 we’ve learned how a Bluetooth Low Energy Service gets pieced together on the Nordic NRF52 SDK. This final post brings together all the elements in an end-to-end working example. Let’s get going! Setting Everything Up Go look at the Readme.md in each of the example repositories. (You will have to clone the repositories, sign up here to get the code)....

So, rather than keeping the status quo, it’s time to do something about it! If you’ve been looking to protect your site visitor’s privacy and improve performance this blog post is for you....

How to Define a Protocol Buffer Bluetooth Low Energy Service: Part 2

This is Part 2 of configuring your own Bluetooth Low Energy Service using a Nordic NRF52 series processor. If you haven’t seen Part 1 go back and check it out. I’ll be waiting right here.. If you’re with me thus far, high five. 🖐 Let’s jump in! So far we’ve created an efficient cross platform data structure using Protocol Buffers. This Protocol Buffer in particular can be used to send these defined data structures a Bluetooth Low Energy Service....

Finding the Best TVOC Sensor: BME680 vs CCS811 vs SGP30

UPDATE! (6/18/2019) I’ve been watching the data over the past month. What i’ve found has definitely changed my opinion about the devices i’m using. So what’s the big news? Temperature The BME680 and the SGP30 both correlate in their readings with temperature. This means when the temperature goes up and down, i’ve seen the TVOC reading go up and down as well. Hardly useful for a sensor that is supposed to tell you if your air is bad or not....

Use The Particle Squared Air Quality Sensor With Google Docs

Air quality. You probably think about it more now that our clean air has turned into a permanent haze across the sky. Yuck. I’ve previously written about the subject. This post is a straight-to-the-point version which will get you up and running quick! Gather the Goods Get everything together that you’ll need for this project. This includes: A Particle Mesh board (Argon, Boron, Xenon). You can get them almost anywhere....

Homemade Particle Powered Indoor Air Quality Sensor

I got my hands on some of the mesh based Particle boards not too long ago. I’ve been itching to try them out but haven’t quite figured out the project. One thing has been bothering me though: air quality. I spend a good amount of time in my office tinkering, soldering, coding and writing. I sneeze occasionally so I always wondered, how bad is it? The house is also prone to mold exposure during the hot months which had me concerned....
