Humidity sensor module HTU(F) 383X

AMSYS: The HTU(F) 3833 and HTU(F) 3835 from the HTU383X series are ready-to-use digital plug and play modules for accurate humidity and temperature measurement with 3 V and 5 V supply. Power consumption during the measurement is typ. 450 μA.

The output signals (I²C) are calibrated, temperature compensated and linearized and do not require additional external components. The humidity measurement range is 0 to 100 % R.H. and the temperature measuring range is -40° to 110° C. The response times, as well as the recovery time (after complete condensation) are in the low second range. The reliability is not affected even with repeated complete condensation.

The humidity measurement modules output the relative humidity and temperature values as digital signals in I²C format. The resolution of the HTU(F) 383X can be set by programming (8 / 12 bit: humidity up to 12 / 14 bit temperature). The accuracy is ± 2 % R.H. in the range between 5 % and 95 % R.H. and the long-term drift is typ. 0.5 % R.H. / year, which are excellent values for humidity measurement.

The new humidity sensor modules feature additional functions which can be set via the software. These are e.g. Battery control, cyclic redundancy check (CRC check), sleep mode and heater function.

The HTU(F) 383X are suitable for applications that require low power consumption (mobile applications). They can be supplied with or without PTFE filter (F) (particle and liquid protection) and are available with cable connection or with a PVBM (Samtec connector).
