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.

This system uses an Arduino UNO with smoke, flame, and temperature sensors (like MQ, KY-026, and DHT11) to detect early signs of fire. If any sensor detects danger—like smoke, high heat, or flame—a ...

This paper aims to enhance vehicle safety by implementing an alcohol detection method to prevent accidents caused by driving under the influence. The approach involves integrating an MQ-3 alcohol ...

AirShield-MQ9 is a fully open-source, Arduino-based LPG leak detection system designed for homes, labs, and small industrial setups. It leverages the MQ-9 gas sensor to detect the presence of lique ...

RTX and Shield AI are working together to bring Shield AI capabilities to certain RTX defence products, such as loitering ...

Scanners for loose papers have become so commonplace that almost every printer includes one, but book scanners have remained frustratingly rare for non-librarians and archivists. [Brad Mattson] had… ...

Optical sensors articles from across Nature Portfolio Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient ...

Installing a smart water sensor can save you a lot of money and hassle. The best models we've tested immediately alert you to leaks and even shut off your home's water supply.

This work focuses on developing an Arduino-based gaming glove that converts hand gestures into real-time game controls using an MPU6050 sensor. Key challenges addressed include ensuring sensor ...

For our DxOMark camera sensor reviews, we measure the image quality performance only of camera sensors that are capable of capturing images in RAW format, and we do this before demosaicing or any JPG ...
