HTU20P(F) is a new humidity and temperature sensor by MEAS.
Setting new standards in terms of size and intelligence, it is embedded
in a reflow solderable Dual Flat No leads (DFN) package of 3 x 3 x 0.9
mm foot print. This sensor provides calibrated, linearized signals in
analog pulse width modulated (PWM) format.
HTU20P(F) humidity sensors are dedicated humidity and temperature
plug and play transducers for OEM applications where reliable and
accurate measurements are needed. These low power sensors are
designed for high volume and cost sensitive applications with tight
space constraints.
PWM signal runs on a base frequency of 120Hz, the data signal is
provided on SDA line. Pulling SCL high or low allows for switching
between humidity and temperature, respectively. The sensor measures
twice per second. The PWM signal may be converted to an analog
ratiometric interface by adding a low pass filter.
With MEAS’ improvements and 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. HTU20 is also available with digital I²C (HTU20D(F).
Optional PTFE filter/membrane (F) protects HTU20P analog 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.
· Full interchangeability with no calibration required in standard conditions
· Instantaneous desaturation after long periods in saturation phase
· Compatible with automatized assembly processes, including Pb free and reflow processes
· Individual marking for compliance to stringent traceability requirements
