Key Takeaways Infrared IR waves are part of the electromagnetic spectrum crucial for various applications by detecting thermal energy emitted by objects IR sensors can be classified as active emitting ...
Particulate content in the air? There’s a sensor for that, too. Someone sneaking up on you? Get yourself some passive infrared sensors (PIRs) and maybe a smart camera just to be sure.
In addition to sensor size and weight, cost also is a constraint. Affordability coupled with size and weight drives performance tradeoffs in development programs, Petito continues. Technology for ...
Abstract: Conventional deformation sensors are inconvenient to deploy in large areas due to the employment of cables and power supplies. This article proposes a wireless passive sensor based on ...
