SF1 filter cap
Filter cap for SHT1x humidity and temperature sensors
Easily mountable solution to protect SHT1x humidity sensors. The SF1 filter cap protects Sensirion’s humidity sensors SHT10, SHT11 and SHT15 against water, dust, soot, particles and other contaminants. It consists of a plastic housing with a water vapor-permeable filter membrane.
The cavity inside the filter cap is designed so that the volume between membrane and sensor is negligible; hence the impact on response time for humidity measurements is reduced to a minimum. The cap is available in white and is made of a single piece of polypropylene (PP) and a filter membrane welded to the single piece.
The filter cap is designed to be mounted after soldering by clipping the two pins on to the PCB and welding them from the back. Together with the sensor, it provides a compact entity that can serve as an adaptor to the device housing. With the addition of adhesive for sealing to the PCB and use of an o-ring, it provides a waterproof mounting solution.
