After a lot of work and preparation I’m excited to announce that the Bee Motion S3 crowdfunding campaign is now live and ready for pre-order! The Bee Motion S3 is an ESP32-s3 powered PIR motion sensor development board that is designed to be easy to use and packed with helpful features.

Open source and easy to use

The Bee Motion S3 supports Arduino, MicroPython, CircuitPython and ESPHome, with example sketches for all of them. The hardware is open source as well. All of that and more is available now on the the projects Github.

I’ve done my best to make it as easy to use and get working in your projects. It’s just waiting for you to put it to good use.
