MEMS Vision Combines Silicon Technolgy With SiC For Sensors
The MVH3000D product line of tiny chips is designed to fulfil the needs of a wide range of applications and markets. These include consumer electronics, health & fitness, industrial, building automation, appliances, and wireless sensing (the internet of things)
MEMS Vision, a supplier of MEMS-based solutions to the global sensing market has launched its most advanced MVH3000D series of digital relative humidity (RH) and temperature (T) sensing chips.
The company maintains that a unique combination of features, programmability, and high performance specs, ensures the most competitive value in the industry.
The high accuracy MVH3001D chips have a ±1.5 percent RH accuracy.
MEMS Vision also says unmatched robustness, reliability, and durability is achieved through the proprietary use of SiC to build and protect the miniature sensors.
These sensors also have high electromagnetic interference protection and are claimed to be the only chips in this class to feature grounded metallic shields.
Apart from the wide range of allowable supply voltages (1.8V - 5.5V), the resolutions of the RH & T readings can be set independently from 8 to 14 bits, for a total of 16 different combinations.
The RH response time is typically 6 seconds for humidity measurements and have a low power consumption of 2μW average power for one RH+T measurement per second in the lowest power mode (1.8V, 8-bit resolution).
Very high temperature accuracy – a temperature accuracy of ±0.20C is guaranteed, over the wide range from -100C to 800C (models MVH3001D and MVH3002D).
The compact devices, shown above, measure 2.4 x 3 x 0.8 mm.
The MVH3000D series features four products, offering a comprehensive choice of RH accuracies, from ±1.5 percent RH to ±3.8 percent RH, and of temperature accuracies, from ±0.20C to ±0.30C.
International customers are currently sampling these new products, and an evaluation kit is now available to experience and assess the full capabilities of these sensors, along with a set of reference designs.
MEMS Vision will showcase the MVH3000D Series at the 2013 Sensors Expo in Rosemont, Illinois, between June 4th and 6th, 2013.
