Scientific devices that can sense physical phenomena—sensors—are nothing new. We are approaching the 400th anniversary of the glass-tube thermometer, for example. Given a timeline that goes back centuries, the introduction of semiconductor-based sensors is quite new, however, and engineers aren’t anywhere near exhausting what is possible with them.
Semiconductor sensors quickly permeated our world, in part because they can be easily integrated with and managed by software. Photodetectors commonly measure the amount of daylight in order to activate lamps; motion sensors activate doors; audio sensors identify specific vocal sounds to initiate a query on the internet.
The current trend is to combine multiple types of semiconductor sensors to create systems able to detect, evaluate and respond to multiple simultaneous conditions. New vehicles use various combinations of visual and range-finding sensors to keep themselves on the road and avoid collisions. Aerial drones rely on a suite of directional, positioning, air pressure, and range-finding sensors to navigate safely.
The scientific principles used in that first glass tube thermometer created nearly 400 years ago have been known for two millennia. People have always been interested in their environment conditions.
In the modern era, semiconductor manufacturers have been creating, perfecting, and learning how to use a wide variety of sensors that can gauge characteristics such as temperature and humidity, and not only detect and measure the presence of gasses and particulates, but also identify specific volatile organic compounds (VOC).
These sensors, too, are being combined in new ways. As we accumulate data showing that air quality can have more significant consequences than previously understood, the ability to monitor the environments we create for ourselves, most notably office buildings, factories, and large campuses.We can provide a variety of parameter specifications of the sensor, welcome to consult.
