RAK12030 Sensing Pad
The sensor contains a sensing pad that you can place the sensor exposed under the open sky where it can be
affected by rainfall and keep your WisBlock solution in a dry place or inside a waterproof enclosure.

RAK12005 Sensor Module
The RAK12005 module produces an output voltage depending on the resistance of the sensing pad. The signal
from the sensing pad is fed to an MCP606 Comparator to digitize it then the comparator output is tied to the IO pin
on the WisConnector. The module also has a built-in potentiometer for sensitivity adjustment of the digital output.
Keep the RAK12005 in a dry place or inside a waterproof enclosure, just make sure not to wet this part of the
module.
