HPP845E031R4 is a HTU21D(F) digital relative humidity sensor with temperature output (I.C 21D RH/T digital). The HTU21D(F) is a new digital humidity sensor with temperature output by MEAS. HTU21D(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. This low power sensor is designed for high volume and cost sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Typical applications include home appliance, medical, printers and humidifier.
