Installing a smart water sensor can save you a lot of money and hassle. The top leak detectors we've tested immediately alert you to issues and even shut off your home's water supply. I’ve been ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Abstract: This paper proposed a self-contained IoT sensor module which includes sensor for collecting various information, micro-computer and multiple solar panels for realizing dynamic cost reduction ...

Abstract: Miniaturization of sound localization sensors arrays is heavily constrained by the limited directional cues in intensity difference and phase difference available at the microscale.

int led = 13; // the pin that the LED is atteched to int sensor = 2; // the pin that the sensor is atteched to int state = LOW; // by default, no motion detected int val = 0; // variable to store the ...
