By pioneering digital humidity sensors 15 years ago, Sensirion has defined an industry standard with the SHTxx series. The new digital SHT3x humidity sensor series takes sensor technology to a new level and sets the next industry standard.
It consists of a low-cost version with the SHT30 humidity sensor, a standard version with the SHT31 humidity sensor, and a high-end version with the SHT35 humidity sensor. The SHT3x humidity sensor series combines multiple functions and various interfaces (I2C, analog voltage output) with a applications-friendly, very wide operating voltage range (2.4 to 5.5V).
The SHT3x offers a range of new features, such as enhanced signal processing, two distinctive and user-selectable I2C addresses, an alert mode with programmable humidity and temperature limits, and communication speeds of up to 1MHz. The DFN package has a footprint of 2.5 × 2.5 mm with a height of 0.9mm. This allows for integration of the SHT3x into a great variety of applications. Additionally, the wide supply voltage range of 2.4 to 5.5V and variety of available interfaces guarantee compatibility with diverse integration requirements.
