HTU3835 digital humidity and temperature sensor by AMSYS

HTU3535 humidity / temperature sensor module

The HTU(F)3535 and HTU(F)3533 sensors in the HTU(F)353X series are analog, ready-to-use, plug-and-play modules for precise humidity and temperature measurement.

The modules output the relative humidity and temperature (NTC) as analog signals which can be easily converted into the corresponding humidity and temperature values using a look-up table.

Humidity and temperature signal response times and the recovery time (following full saturation) are within a range of a few seconds. A supply voltage of 3 V or 5 V is needed.

The HTU(F)353X is ideal for applications which have a low current consumption. They are supplied as standard models with a PTFE filter (F) and particle and liquid protection.


Variants of the HTU(F)353X

  • HTU(F)3535PVBM: with a medium male connector (thru hole)
  • HTU(F)3535W100G26 with a cable (length: 10 cm, 26 AWG)
  • The HTU(F) modules are supplied in a 3-V version (HTU(F)3533) or as a 5-V variant (HTU(F)3535).
  • The HTU family also includes the digital HTU353X version and OEM sensors for reflow assembly: HTU21DHTU21P and the inexpensive  HTU20D and HTU20P.
