HPP845E131R5 is a HTU21D(F) RH/T sensor IC. It is a new digital humidity sensor with temperature output by 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 0.11inch x 0.11inch x 0.03inch footprint. This sensor provides calibrated, linearized signals in digital, I²C format. HTU21D(F) digital humidity sensor is 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. Lot identification is printed on the sensor and an electronic identification code is stored on the chip. Applications include home appliance, medical, printers and humidifier.
