SGPC3 – Air Quality Sensor for Battery-Driven Applications

Sensirion, the expert in environmental sensing, now offers the ultra-lower power gas sensor SGPC3. The SGPC3 makes indoor air quality sensing available for mobile and battery-driven applications. With an average supply current of less than 0.07 mA the SGPC3 is able to provide indoor air quality measurements with several years of battery lifetime. Based on Sensirion’s SGP multi-pixel platform the SGPC3 offers a complete gas sensor system integrated into a very small 2.45 x 2.45 x 0.9 mm3 DFN package featuring I2C interface and a fully calibrated and humidity-compensated air quality output signal

Sensirion’s MOXSens® Technology provides the SGPC3 with an unmatched robustness against contamination by siloxanes resulting in outstanding long-term stability and accuracy. The combination of ultra-low power consumption and long-term stability makes the SGPC3 the perfect choice for indoor air quality monitoring in mobile and battery-driven smart home applications. Evaluation and testing is supported by application notes and example code; the SGP evaluation kits are also available through Sensirion’s distribution network.

Sensirion Presents Pressure-Resistant Mass Flow Meter

The SFM4200 mass flow meter is a new star in the Sensirion range. Thanks to its high pressure resistance, it can be operated at pressures of up to 8 bar and measures flow rates up to 160 slm with a rapid signal processing time of 0.5 ms. It is particularly suitable for gas mixing in medical applications.

Sensirion is one of the leading manufacturers of innovative sensors and sensor solutions that millions of people rely on every day. With the launch of the SFM4200 digital mass flow meter, Sensirion has once again underscored its commitment to innovation. The SF4200, which measures air, oxygen and other non-corrosive gases with an outstanding level of accuracy, is pressure-resistant than its predecessors and can be operated up to 8 bar pressure, while delivering reliable and precise measurements. With a signal processing time of 0.5 ms, the sensor is incredibly fast, as well as highly accurate. Its pressure resistance makes it ideally suited to high-volume medical applications such as oxygen gas mixing in respiratory applications, where the sensor is integrated into the high-pressure side. Customers can therefore install the SFM4200 flexibly, allowing them to use it to significantly develop their own products or to transform the design. (more…)

The top 10 humidity sensors

Elizabeth Bustamante @ snapeda.com compiled a list the top 10 humidity sensors available today. Most of the sensors on the lists are from Honeywell, but surprisingly the top sensor comes from Sensirion. She writes:

Air humidity is an important factor to consider when designing an electronic device. Having too much humidity in the environment can cause condensation and corrosion, which can lead to anomalies in performance or even failures.

To prevent this, engineers use humidity sensors. These devices are used in systems deployed in humid environments, such as industrial control, instrumentation, climatology, and agriculture applications.

Most Accurate Digital Temperature Sensor STS35

Sensirion, a leading provider of environmental and flow sensor solutions, presents the STS35 temperature sensor – the most accurate sensor of the versatile STS3x series. The high-accuracy temperature sensor has been designed to fulfill the needs of demanding markets such as the medical and automotive sectors. Typical applications include body temperature measurement and temperature control.

The new STS35 temperature sensor is a high-end model in the STS3x series and has an outstanding temperature accuracy of DT = ± 0.1°C. Like all STS3x series models, the sensor features increased intelligence and reliability. Its functionality includes enhanced signal processing, two distinctive and user-selectable I2C addresses and communication speeds of up to 1 MHz. The DFN package can be integrated into an extensive variety of applications thanks to its footprint of 2.5 x 2.5 x 0.9 mm3 and the wide supply voltage range of 2.4 V to 5.5 V. Furthermore, the STS35 sensor includes a configurable alert function, allowing it to be used as a temperature watchdog. Like all sensors by Sensirion, the STS3x is based on the unique CMOSens® Technology that integrates the sensing element and read-out electronics onto a single chip, enabling high production volume at an exceptional price/performance ratio.

The First and Only Long-Term Stable Metal-Oxide Gas Sensor

At this year’s Sensor+Test 2017 in Nuremberg (May 30 – June 1), Sensirion AG, the expert in environmental and flow sensor solutions, introduces the SGP – the first and only long-term stable metal-oxide gas sensor.

The SGP gas sensor is based on Sensirion’s multi-pixel platform, which integrates four gas sensing elements into a very small 2.45 x 2.45 x 0.9 mm3 DFN package featuring a fully calibrated air quality output signal. The unprecedented combination of long-term stability and multi-pixel technology opens up new possibilities for environmental monitoring in smart home, appliances and Internet of Things applications. Thanks to its unique performance, the SGP allows for the first time the integration of metal-oxide gas sensors into mobile devices.

New Ultra-Small Digital Humidity Sensor: Simplicity Meets Proven Performance

Sensirion_Humidity_SHTW2_300dpi

Sensirion, the world’s leading manufacturer of humidity, temperature and flow sensor solutions, presents its second generation WLCSP (wafer-level chip-scale package) humidity sensor: the SHTW2. The SHTW2 humidity sensor comes in a flip chip package – an established technology that represents one of the simplest and smallest possible ways of packaging a semiconductor chip and results in a tiny footprint of 1.3 x 0.7 x 0.5 mm3. The SHTW2 also pioneers a new category of ultra-small humidity sensors suitable for applications with the tightest space constraints.

The SHTW2 is based on Sensirion’s CMOSens® Technology, which offers a complete sensor system on a single chip with a digital I2C interface. The sensor is fully calibrated and covers a humidity measurement range of 0 to 100% RH and a temperature measurement range of -30 to 100 °C, with a typical accuracy of ± 3% RH and ±0.4 °C. The operation voltage of 1.8 V and the low power consumption make the SHTW2 perfect for integration in consumer electronics that run on the tightest power budgets, such as mobile phones, wearables and Internet of Things (IoT) applications. With the industry-proven quality and reliability of Sensirion’s humidity and temperature sensors, and constant accuracy over a large measurement range, the SHTW2 offers an unprecedented price-performance ratio. Tape and reel packaging and suitability for standard SMD assembly processes ensure the SHTW2 is ideal for high-volume applications.
