Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Synthesis of nanostructured cubic phase SnO 2 thin film and its trace-level sensing of CO gas This study presents a cubic phase SnO 2 thin film gas sensor with ultra-high CO sensitivity and 1 ppb ...

The Smart EcoBin is an intelligent waste management system designed to promote environmental sustainability and improve the efficiency of waste collection. Equipped with multiple sensors, the system ...

When running node-dht-sensor on a Raspberry Pi 5 (or newer), you must install libgpiod (and its development headers) before you build. If you try to install the module with --use_libgpiod=true without ...

Abstract: Over the last three decades, a large number of evolutionary algorithms have been developed for solving multi-objective optimization problems. However, there lacks an upto-date and ...

Abstract: Most industrial system failures are caused by engine failure that can be very serious and cause significant downtime. Therefore, continuous health monitoring, accurate fault detection and ...

Unexpected electricity bills can often be frustrating. This smart energy monitor, built using an ESP32 microcontroller, measures real-time power consumption and predicts upcoming bills with the help ...
