Digital Temperature and Humidity Sensor HTU20D 

DESCRIPTION 

HTU20D(F), is a new digital humidity sensor with temperature output of MEAS. Setting new standards in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a small 3 x 3 x 0.9 mm foot print. This sensor provides calibrated, linearized signals in digital, I2C format.

HTU20D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the module for humidity and temperature digital outputs. These low power sensor are designed for high volume and cost sensitive applications with tight space constraints.
