Biosensing

Biosensing is sensing and transmitting information about a biological process of an individual under observation. Two common technologies used are: Bio-potential biosensing - most commonly used when information is desired about living tissue - such as heart, brain, and muscle activity; and Optical biosensing - most commonly used in pulse oximetry (SP02) applications and optical-based heart rate monitors.

Chemical

pH sensing is used to monitor water quality by measuring the concentration of hydrogen ions in a solution. The various ways to sense these items are chemical sensing: highly integrated, low-power analog front ends (AFE) for pH sensors; optical: specialized spectral filtering can be combined with a light sensor to measure unique transmission/absorption signatures of some chemicals and materials; intelligent wavelength sensing: DLP® technology provides intelligent, programmable wavelength selection filter eliminating the need for expensive array detectors, resulting in high performance at lower price points with a small form factor.

Current/Power

Current measurement is aimed at understanding the consumption by a load, whether the entire system or individual voltage rails. In addition to measuring the current, many systems want to understand the supply voltage rails along with the current to calculate the overall system power consumption.

Flow
Many end use equipment in a number of markets need to accurately measure the flow of fluid, heat, and gases for metering or process control applications. Whether it is a water meter for a residential or industrial utility, gas meter or process control meter for heating and cooling of critical systems, the flow must be accurately measured for proper billing and system control. These systems often are in remote locations with monitoring powered by a battery source and require a low-power and highly accurate sensing technology.

Gas/Fluid
Gas-sensing applications detect the quantity and level of gas in the environment, including toxic gases, oxygen, carbon dioxide, methane, and carbon monoxide. Air quality in health and safety applications are becoming an important factor especially in the building automation and automotive markets.

Humidity
Humidity sensors determine the amount of water vapor / moisture in the air. Because relative humidity is a function of temperature, humidity sensors also usually include integrated temperature sensors.

Level

Many products in many markets make use of water, oil, fuel, and other fluids. Whether it is water in a coffee maker, fuel in an automotive tank, or chemicals in a factory process, the performance and lifetime of these systems rely on knowing the level of fluid present at any time. Because different systems have different requirements for accuracy, cost, reliability, and sensor location, there are several technologies to address the level sensing application.

Light

Optical sensing is the conversion of light rays into electronic signals. Often the intensity of light or changes between one or more light beams is being measured. In its simplest form, sensing light intensity is used for lighting controls in everything from tablets/phones to building automation and street lighting. Optical sensing is used in broad range of applications. By monitoring spectrum, phase, geometry, or timing, optical sensing enables advanced applications such as chemical analysis, 3D mapping, medical scanning, and pulse oximetry.
