The BME280 sensor was easier to set up, as it communicates over the I2C serial protocol. This means that we only needed to connect power, ground and two communication wires to the sensor.

Israeli scientists have developed a gas sensor that can distinguish “mirror image” molecules in the air, a breakthrough with the potential to revolutionize medical diagnostics, food and beverage ...

David Ly is the founder of Iveda, having served as CEO and Chairman of the Board of Directors since the company’s inception in 2003. The oil and gas industry has always been about balancing scale, ...

In my professional life I have used many different gas analyzers for confined space entry as well as emergency response. These units are very expensive and require the user to be able to read the ...

For many industries, nitrogen (N₂) plays an unnoticed but vital role in inerting reactors, storing food safely, and protecting the sterility of pharmaceuticals. But what makes it dangerous is that ...

The passive PT-symmetric model for SAW sensor. a The schematic diagram of the coupled resonators model and the real part of the eigenfrequency surfaces in the parameter space (ω1=ω2=ω0=0,γ0=0). The ...

A new laser-based device can scan almost any sample of gas and detect its molecular ingredients down to concentrations in the parts per trillion. Expert sommeliers can take a whiff of a glass of wine ...

Expert sommeliers can take a whiff of a glass of wine and tell you a lot about what’s in your pinot noir or cabernet sauvignon. A team of physicists at CU Boulder and the National Institute of ...

Scientists use devices known as frequency comb lasers to search for methane in the air above oil and gas operations and to screen for signs of infection in human breath. A new study could help make ...
