Here is the outdoor/indoor moisture sensor cover for product :
The sensor comes very tied to the case, push firmly the sensor into the case.
It does not cover the board coming with the sensor. If use the analog read you don't need it, connect directly to microcontroller, just put 10k resistor between 3.3v and analog port. Or better use the extra port instead of 3.3v to save battery and slow oxidation:
-----<< PortN (set HIGH before analog read, set LOW after
| read)
| | 10K
| |
|
<<--------------------->> Analog Port (analog read)
To Sensor
