Humidity & Temperature sensor - HTU21D
1.Product Description:
HTU21D, the new digital humidity sensor with temperature output 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 3 mm foot print and 0.9 mm height it provides calibrated, linearized signals in digital, I²C format.
HTU21D 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 humidity and temperature digital outputs. HTU21D digital humidity 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 digital humidity 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.
