Bee Motion S3 - A portable, open-source PIR motion detection board for ESP32-S3

If you're looking for a motion sensor that can do more than detect motion, you might want to take a close look at the Bee Motion S3. It is one of the best ESP32-S3 boards in terms of features.

Bee Motion S3 comes with a built-in PIR sensor and you can use it as an access control device or as a wireless doorbell. You can connect it to an ultrasonic sensor to detect people and avoid false triggers like animals or objects that move around during windy weather. This makes it an ideal choice for home automation projects. 

The Bee Motion S3 is a compact, open-source ESP32-S3 PIR motion sensing board that is ideal for home and industrial automation projects.

The module can be powered via USB or a battery. The module also has UART (for debugging) and I2C interfaces.

The Bee Motion S3 can measure ambient light intensity which is important when designing automation systems.

With its modest, compact form, the Bee Motion S3 is intended to make PIR motion detection applications in buildings as simple as possible. You might use the PIR, RGB LED, and ambient light sensors on the Bee Activity S3 to create a battery-operated night light, programme your soldering iron to switch off when it no longer senses motion, or install one next to your pet's food bowl to get alerts on their feeding habits.

The Bee Motion S3 is a feature-rich ESP32-S3 with a built-in PIR motion sensor that makes building your motion detection-based prototype easy.

Another self-contained motion-sensing development board, this one based on the Espressif ESP32-S3, is being prepared for a crowdfunding campaign by Smart Bee Design. It is called the Bee Motion S3.

It is the perfect device for detecting movement in your living room, kitchen, bedroom, or any other place. The sensors on this module are superbly sensitive to even small changes in light and noise.

The ESP32-S3 is used on other Bee Motion boards besides this one. The Bee S3 was introduced by the business before the end of last month with the goal of providing "an ultra-low-powered ESP32 [that is] inexpensive" and suitable for battery-powered projects. In contrast, the previous Bee Motion, like its predecessor, the little Bee Motion Mini, used an ESP32-C3 processor based on the free and open-source RISC-V instruction set architecture.

In the near future, Smart Bee Design will begin a crowdfunding campaign for the board on Crowd Supply. Schematics and source code for the project is accessible on its GitHub repository under the permissive MIT licence.
