Vapor cell measuring about half a centimeter in length. Researchers at CU Boulder and the National Institute of Standards and Technology are developing sensors based on technologies used in chip-scale ...

[hclxing] eagerly picked up an LED ceiling light for its ability to be turned on and off remotely, but it turns out that the lamp has quite a few other features. These include adjustable brightness, ...

Microwave sensors detect electromagnetic waves at frequencies starting from ~300 MHz up to the terahertz range. They allow us to survey remote terra incognita and detect faint radiations from distant ...

London and the National Physical Laboratory (NPL) has successfully used microwaves to measure blood-based molecules known to be influenced by dehydration. (Phys.org) —Can your microwave oven power ...

Microwave-based wireless power transfer is revolutionizing how energy reaches remote and hard-to-access devices, enabling ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication.

New research developed a new microwave radiation sensor with 100,000 times higher sensitivity than currently available commercial sensors. Researchers said better detection of microwave radiation will ...

Dear Jim: I plan to use my microwave oven more, instead of the range/oven, to save electricity. I gave my old microwave to my mother and I need a new one. What should I look for in a new one, which I ...
