How it works is simple: you can track devices using Bluetooth on the ESP32, and through a combination of presence and signal strength, you can define a sensor that changes to an "on" state when your ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...

This breadboard compatible package combines an ESP32-S2 module with a top-mounted PIR sensor, making it a turn key solution for all sorts of motion sensing projects.

As Hackaday revealed, this one comes with an E Ink display, a secondary OLED panel, and a keypad made of soft silicon that is encased within a see-through case.

He’s using the ESP32 and some off-the-shelf modular components to create an Internet-connected air quality monitoring station.

It’s a pocket-sized device with an E Ink display, a thumb keyboard, and simple software that’s currently designed for note-taking and not much else.

While some details haven’t been finalized yet, the basic elements include an ESP32-S3 system-on-a-chip combined with a small E Ink display and a custom printed circuit board with a QWERTY keyboard.

The CL-32, his latest creation, features an E Ink display powered by an ESP32-S3 SoC. Further, the device also offers GPIO ports should you wish to add some other peripherals.
