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 ...

Abstract: We have developed a new readout circuit for highly sensitive CMOS image sensors. The circuit makes it possible to obtain a high signal-to-noise ratio by effectively transferring signal ...

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.
