SHT30 Datasheet | Sensirion

features its all-new flagship sensors from the SHT4x family, which profit from about two decades of RH/T sensor development. Dedicated to best-in-class performance, smallest footprint, and attractive pricing, our new SHT4x sensors are the products of choice for many SHT3x applications. In particular, the SHT4x outperforms the SHT3x in every aspect and offers versatile add-ons, such as a powerful heater for self-decontamination, conformal coating protection, or filter membranes. Moreover, the latest analog output circuitry enables reduced the PSRR (Power Supply Rejection Ratio) and further increase of the driving strength of the load.
