Courtesy: SensirionSensirion SHT3x series of humidity sensors features a filter membrane that is designed to protect the sensor opening from water and dust. The cover allows the sensor to be used in harsh environmental conditions where spray water and high exposure to dust is common. The membrane cover is attached to the sensor package by a double-faced adhesive tape and the sensor is designed to withstand multiple reflow cycles. Due to minimal package volume and the membrane’s high water vapor permeability, the response time of the relative humidity and temperature signal is identical to the value achieved by the uncovered sensor. The sensors also feature signal processing, two user-selectable I2C addresses and communication speeds of up to 1 MHz. The DFN package can be integrated into a broad variety of applications.
