Product Description:
HTU20D(F) Sensor Digital Relative Humidity Sensor With Temperature Output
Features:
DFN type package
· Relative Humidity and Temperature Digital Output, I²C
interface
· Fully calibrated
· Lead free sensor, reflow solderable
· Low power consumption
· Fast response time
DESCRIPTION
HTU20D(F), 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.
HTU20D(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 humidity and temperature digital outputs. HTU20D(F) 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
HTU20D(F) 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.
Optional PTFE filter/membrane (F) protects HTU21D digital humidity sensors with temperature output against
dust, water immersion as well as against contamination by particles. PTFE filter/membrane preserves a high
response time. The white PTFE filter/membrane is directly stuck on the sensor housing.
