Building an occupancy sensor with a $5 ESP32 and a serverless DB
Matt didn’t think he would “design a full end-to-end software solution to collect occupancy data across a college campus” but he ended up doing just that. This project collects BLE beacons from nearby devices, as a count for occupancy, and sends it back to a time series database for analysis. - Matthew Science Blog

Breaking Free from DRM: The Story of Hacking My Air Purifier
An investigation into the Xiaomi 4 Pro’s DRM’d Air Purifier - Unethical
Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
