Abstract: In this paper, a hand gesture detection and classification system using two differential Pyro-electric Infrared (PIR) sensors and a camera is introduced. Motion presence is investigated in ...

This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the ...

The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.
