Humidity Sensor 

We decided we wanted to use a humidity sensor in our can as CanSat is supposed to simulate a space mission. Humidity sensors are frequently used in space missions to test for water. 

After much research we found that the HH10D humidity sensor, was the right one for us. We decided to go with this sensor as it is relatively accurate (+-3%) and the code would be straight forward. 

I started straight into the code and quickly realised that the tutorial I was hoping to use was based on previous Arduino software and was completely useless. After a bit more research and consultation with our mentor Cathal and our physics teacher Frank, we established a new, more accurate code for the sensor. 

This weekend I'm travelling out to Shannon Airport again to calibrate the sensor.
