Humidity, Temperature, Pressure and Gas Sensors Set Performance Benchmarks

At this year’s edition of Sensors Expo, Sensirion will exhibit new and refined sensor solutions for measuring humidity and temperature, differential pressure, gas and liquid flow. Visit booth 423 and learn more about these products:

Most Accurate Digital Humidity Sensor

The new SHT35 humidity sensor is the high-end version of the SHT3x series and has an outstanding accuracy of 1.5% RH (relative humidity) and a temperature accuracy of ΔT = ±0.2°C. Like all SHT3x 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 a broad 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.

Protective Cover for SHT3x Humidity Sensors

The SHT3x protective cover is an optional polyimide foil directly attached to the top surface of the sensor. It covers the SHT3x’s complete sensing area and thus acts as a reliable shield against pollution during SMT assembly of the sensor and subsequent processes, such as conformal coating or potting. The protective cover is designed to withstand multiple reflow soldering cycles. To enable correct sensor operation, it must be removed after assembly.

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

The new 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. 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.

World’s Smallest Differential Pressure Sensor: Creating Space for Your Ideas

The new SDP3x sensor boasts incredible small size. It measures just 5 x 8 x 5 mm3, opening up new dimensions of integration and application possibilities. Like all Sensirion differential pressure sensors, the SDP3x features excellent accuracy and long-term stability and has no zero-point drift. Furthermore, the SDP3x sensor is reflow solderable and provides extended functionality such as multiple I2C addresses and interrupts. All this makes Sensirion’s new differential pressure sensor to the perfect choice for high volume and cost-sensitive applications where size is essential.
