Sensirion SHT-11 humidity and temperature sensor ready to go!

One of the sensors that can be read by the Neptune module is the Sensirion SHT-11 I have had laying about for years.

Now finally it is ready for use! The sensor sits on the end of a 2,5 meter cable which is soldered on directly. A small capacitor is glued on as well to cope with the excessive cable length. The sensor in its entirety is covered in a drop of silicon glue to keep the moisture out of the electronic contacts. This sensor will be measuring over 98% relative humidity at times!

The Sensirion SHT-11 sensor glued into a drop of silicone. This digital sensor measures air temperature and relative humidity in the Paludarium.

So far the results are looking good. This is the sensor still hanging in the living room:

22.24 degrees centigrade and 65.94% relative humidity. Sounds realistic as it’s a very moist day.

When the silicone had dried, I put the sensor inside the paludarium. After settling it showed measurements like these:

Great! Tempereature at 23.16 degrees, relative humidity at 87,61%. Very Jungley 🙂

What I did find out, is that the location of the sensor heavily influences the measurements. Especially the humidity is VERY dependent on where you measure.
