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 ...

The DS18B20 library supports only the DS18B20, only one sensor per pin, no parasite mode, no Fahrenheit and no alarm functions. The only feature the class supports is the asynchronous reading of the ...

The body sensor network (BSN) system allows communication among sensor nodes attached to different parts of human body to monitor body motion and vital parameters. BSN system using wired network is ...

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 ...
