Installing a smart water sensor can save you a lot of money and hassle. The best leak detectors we've tested immediately alert you to issues and even shut off your home's water supply. I’ve been ...
If you’ve ever come home to a soggy basement or found out too late that your kitchen sink or toilet has a slow leak, you know how expensive it can be to repair or replace carpets, flooring, and walls ...
I’ve tested a lot of stuff in my time – TVs, Christmas trees, vacuums designed for ease – but few things have stuck around like my SimpliSafe home security system. Halloween consistently brings a jump ...
Abstract: A Graphene-based surface plasmon resonance sensor is proposed for rapid water salinity concentration detection and operates with a new multiple light source technique. The proposed sensor ...
Abstract: Differential-output D-dot sensor is indispensable to monitor the performance of the pulsed power facility. The sensitivity of the D-dot monitor is determined by the capacitance of the sensor ...
Thanks to smart security systems, it's easier and more affordable than ever to monitor your home from pretty much anywhere. At PCMag, we have been reviewing smart home security solutions for nearly 20 ...
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 ...
Green algae production is crucial in aqua-agriculture due to its roles in wastewater treatment, CO2 absorption, and oxygen release, along with its potential for valuable product synthesis. Monitoring ...
