A long-term stable metal-oxide gas sensor

The SGP gas sensor is a multi-pixel platform, which integrates four gas sensing elements into a very small 2.45 x 2.45 x 0.9 mm3 DFN package featuring a fully calibrated air quality output signal. The combination of long-term stability and multi-pixel technology opens up new possibilities for environmental monitoring in smart home, appliances and Internet … Continue reading A long-term stable metal-oxide gas sensor

Testing the performance of semiconductors with light

Semiconductors are the cornerstone of modern electronics. They’re used in solar cells, light emitting diodes (LEDs), microprocessors in laptops and cell phones, and more. Most of them are made of silicon, but silicon has its limitations. So for decades researchers have been exploring new materials with properties that make them good candidates for better, lighter, … Continue reading Testing the performance of semiconductors with light

How to keep your mobile phone connected when the network is down

When Tropical Cyclone Debbie hit Queensland this week, one of the casualties was the region’s mobile phone network. Phone towers can stop working because they have been damaged by the wind, or because they have run out of diesel to run their generators. Whatever the cause, the end result is the same: a number of … Continue reading How to keep your mobile phone connected when the network is down

10 ways a position sensor can mess up your project

Position sensors are a common component in many engineering projects. Measuring position or speed accurately and reliably is a tricky business. Selecting the wrong sensor or designing the wrong installation often results in overly complex design, poor performance, high cost or unreliability. 1.Misunderstanding the measurement performance There are 3 key parameters for position sensors – resolution, … Continue reading 10 ways a position sensor can mess up your project
