HTU20-PF (with PTFE filter membrane)
Because of his modular structure consisting of a
capacitive polymer measuring cell and a special developed signal
conditioning ASIC the HTU20P provides a high
accuracy, a low hysteresis and temperature drift and also an
excellent long time stability. The output signal is a 120Hz
PWM-signal, which can be transformed by an additional low pass
filter in an analogue DC-output signal. Through the pin-programming
(SCK to VDD or SCK to GND) the output can be switched between a
relative humidity and a temperature value.
The HTU20P is a low-power-sensor with a maximum
current consumption of 14µA/3Volt, so that he is suitable for
mobile applications. The extended measuring range for relative
humidity is between 0 and 100%. The accuracy varied to ±3 in
the range of 20-80% (@25°C) up to 5% in the extended range.
Temperature range is characterized by ±0.3°C (@25°C)
und covers the range between -40 and +125°C. Relative humidity
and temperature resolution constitutes by 10bit respective 12bit.
After long term saturation phase the operating state of the HTU20P
is operational after 10 seconds.
The sensor is packaged in a reflow solderable Dual Flat No leads
(DFN) housing. The 3x3x0.9mm³ foot print allows a construction
of sensor systems with small dimensions.
With made improvements and the miniaturization of the sensor the
performance-to-price ratio has been improved.
For Protection against dust, liquid film and contamination the
humidity/temperature sensor HTU20P is also
available with a PTFE filter/membrane as the version HTU20P(F).
