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.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
