HTU21D(F) RH/T SENSOR IC. Digital Relative Humidity sensor with Temperature output

The HTU21D(F) is a new digital humidity sensor with temperature outputby MEAS. Setting new standards in terms of size and intelligence, it isembedded in a reflow solderable Dual Flat No leads (DFN) package witha small 3 x 3 x 0.9 mm footprint. This sensor provides calibrated,linearized signals in digital, I2C format.

HTU21D(F) digital humidity sensors are dedicated humidity andtemperature plug and play transducers for OEM applications wherereliable and accurate measurements are needed. Direct interface with amicro-controller is made possible with the module for humidity andtemperature digital outputs. These low power sensors are designed forhigh volume and cost sensitive applications with tight space constraints.

Every sensor is individually calibrated and tested. Lot identification isprinted on the sensor and an electronic identification code is stored onthe chip – which can be read out by command. Low battery can bedetected and a checksum improves communication reliability. Theresolution of these digital humidity sensors can be changed by command(8/12bit up to 12/14bit for RH/T).

With MEAS’ improvements and miniaturization of this sensor, theperformance-to-price ratio has been improved – and eventually, anydevice should benefit from its cutting-edge energy saving operationmode.

Optional PTFE filter/membrane (F) protects HTU21D digital humiditysensors against dust and water immersion, as well as againstcontamination by particles. PTFE filter/membranes preserve a highresponse time. The white PTFE filter/membrane is directly stuck on thesensor housing. This membrane is allowing an IP67 compliantprotection.
