Product Description

Description:

HTU21D, the new humidity and temperature sensor of MEAS 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 1mm height it provides calibrated, linearized signals in digital, I²C format

HTU21D 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 humidity and temperature digital outputs

HTU21D sensors are low power consumption designed for high volume and cost sensitive applications with tight space constraints

Every sensor is individually calibrated and tested

Lot identification is printed on the sensor and an electronic identification code is stored on the chip, which can be read out by command

Furthermore, the resolution of HTU21D sensor can be changed by command (8/12bit up to 12/14bit for RH/T), low battery can be detected and a checksum improves communication reliability

With made improvements and the miniaturization of the sensor the performance-to-price ratio has been improved – and eventually, any device should benefit from the cutting edge energy-saving operation mode
