Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

Your car's tire pressure monitoring system (TPMS) can fail, but you can still drive. Learn why sensors break and what to do when they stop working.

One of the most important measurements we make while tuning an engine is finding out what the actual balance of air and fuel was inside the engine. It doesn’t matter if we have a carburetor, port ...

From leveling shelves to reducing eye strain, these clever tricks will make you see your device in a whole new light ...

A common sight in ‘smart homes’, door sensors allow you to detect whether a door is closed or open, enabling the triggering ...

Abstract: In wireless sensor networks (WSNs), the coverage hole problem is one of the challenging problems that needs an effective solution. Data routing protocols in WSNs aim to disseminate the ...

Abstract: An open-cavity optical fiber gas pressure sensor based on the Vernier effect is proposed. The sensor consists of two Fabry-Perot interferometers (FPIs) connected in parallel. As a sensing ...

Massive cuts to global health-care funding have had a huge impact on the continent, but a more resilient system can be built from within.

This project uses python, flask, docker-compose and redis to create a simple web server to display the latest historical values from the sensor. The sensor reads two particulate matter (PM) values.
