SHT31 Datasheet | Sensirion

Datasheet Membrane Option For SHT3x Humidity and Temperature Sensors - Protects the sensor from water and dust according to IP67 - Allows for sensor use under harsh environmental conditions - Withstands multiple standard reflow cycles - Lasts over total sensor life time - Delivered in T&R Packaging - On-package membrane protected by exclusive license for several patents1 Product Summary The SHT3x membrane is a PTFE foil, dedicated to protect the sensor opening from water and dust according to IP67. It will thus allow for sensor use under harsh environmental conditions, where spray water and high exposure to dust is challenging for accurate sensor performance. The membrane cover is attached to the sensor package by a double faced adhesive tape, which Datasheet: Intention of Use This datasheet is meant to provide all relevant specifications for the additional membrane option of the RH&T-sensors of type SHT3x. All SHT3x products ing with the membrane option are listed in Table 1, is designed to stay on the package over the whole sensor life time. Due to the minimum enclosed air volume, the response time of the RH signal is the same as the value achieved by the uncovered sensor. Sensirion holds an exclusive license for several patents for employing an on-package filter membrane on a humidity sensor1. together with their respective order number. Any further information about sensor performance, munication protocols etc. are to be found in the respective main datasheets, only. 1 General information The SHT3x membrane is an optional PTFE foil, directly attached to the top surface of the sensor. It is attached to the sensor via a double faced adhesive tape, designed to last over the whole sensor life time. The membrane pletely covers the sensor opening and thus acts as a reliable shield against pollution from spray water and dust, classified IP67. The whole package withstands multiple reflow cycles. Although the membrane provides water and dust protection according to...
