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 ...

Activity/gesture recognition using wearable motion sensors, also known as inertial measurement units (IMUs), provides an important context for many ubiquitous sensing applications. The design of the ...

Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to trigger ...
