This is a simple outdoor housing for the Monoprice 4-in-One multisensor. It provides a small amount of additional protection over the stock mount by putting a small "roof" around the sensor and by adding drain holes at the bottom for moisture to escape from.

I can't guarantee that your sensor will survive being used in this, but it'll be interesting to find out!

Let me know how it goes for you.
