www.DataSheet4U.com Datasheet SHT21 Humidity and Temperature Sensor      Fully calibrated Digital output, I2C interface Low power consumption Excellent long term stability DFN type package – reflow solderable Product Summary SHT21, the new humidity and temperature sensor of Sensirion is about to set new standards in terms of size and intelligence: Embedded in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3mm foot print and 1.1mm height it provides calibrated, linearized signals in digital, true I2C format. With a completely new designed CMOSens® chip, a reworked capacitive type humidity sensor and an improved band gap temperature sensor the performance has been lifted even beyond the outstanding level of the previous sensor generation (SHT1x and SHT7x).
