Microelectromechanical Systems: Tiny Tech With Major Impact

Microelectromechanical systems, or MEMS, are generally comprised of components less than 100 micrometers in size, and a standard MEMS device typically measures between 20 micrometers and 1 millimeter.

Scientists and industry leaders have been aware of the high potential of micro machines since the 1950s; manufacturing technology simply needed to catch up. For example, today’s MEMS are built with modified semiconductor device fabrication technologies, such as wet etching, molding, plating, dry etching, and electro-discharge machining.

MEMS Vision Series MVH3200D: High-Performance Digital Humidity Sensors

The team at MEMS Vision specializes in innovative small devices and components, crafting some of the world’s leading nanotechnology. Their unique line of relative humidity and temperature (RH & T) products are made with breakthrough MoSiC™ micro/nanotechnology, and are designed to serve a wide range of original equipment manufacturer (OEM) applications. All sensors are backed by expert engineering techniques for optimal performance and minimal time to market. 

The MVH3200D line of miniaturized digital humidity sensors, in particular, is engineered for unparalleled accuracy. These smart sensors can be independently programmed for customized humidity and temperature resolutions, providing maximum flexibility alongside full calibration. MVH3200D sensors can also provide standard digital I2C outputs to enable plug-and-play integration.

The micro-Watt levels of power demanded by MVH3200D products make them an ideal choice for portable and remote applications, or any situation requiring minimal power consumption.

Available sensor models include:

  • MVH3201D (10% to 90% RH range, ±1.5% RH accuracy)
  • MVH3202D (10% to 90% RH range, ±2.0% RH accuracy)
  • MVH3203D (20% to 80% RH range, ±2.5% RH accuracy)
  • MVH3204D (20% to 80% RH range, ±3.5% RH accuracy)
