This paper presents an optimized wind energy harvesting (WEH) system that uses a specially designed ultra-low-power-management circuit for sustaining the operation of a wireless sensor node. The ...

Build a simple LPG gas leakage detector using Arduino and MQ-5 sensor. This beginner-friendly project features buzzer and LED alerts, circuit diagram, and complete Arduino code for home safety.

We analyze the optical wireless sensor network system using corner cube retroreflectors (CCRs). A CCR consists of three concave mirrors. When a light beam enters the CCR, it bounces off each of the ...
