05-05-2016 | Sensirion | Test & Measurement

Latest from Sensirion is the SHT35 humidity sensor - the most accurate sensor of the versatile SHT3x series and capable of outperforming all similar sensors currently available, says the company. 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 ?T = ±0.2C. 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 1MHz. The DFN package can be integrated into a broad variety of applications thanks to its footprint of 2.5mm x 2.5mm x 0.9mm and the wide supply voltage range of 2.4V to 5.5V. Furthermore, the SHT35 sensor includes a configurable alert function, allowing it to be used as a humidity and temperature watchdog. The SHT3x is based on the unique CMOSens Technology, which integrates the sensing element and read-out electronics onto a single chip, enabling high production volume with an exceptional price / performance ratio, says the company.
