HTU20D(F), is a new digital humidity sensor with temperature
output of 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 3 x 3 x 0.9 mm foot print. This
sensor 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 for humidity and temperature digital outputs. These low
power sensor are 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. Low battery can be detected and a checksum
improves communication reliability. The resolution of these
digital humidity sensor can be changed by command (8/12bit up
to 12/14bit for RH/T).
With MEAS’ improvements and miniaturization of this 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 HTU20D digital
humidity sensors against dust and 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. This
membrane is allowing an IP67 compliant protection.
