This is a protective housing for the Ambient Weather WH31P Water Proof Probe Temperature Sensor. I have a metal building that wouldn't allow me to place my sensor inside so I created this to hang on the door sill outside and sense the temperature inside my shop. I also used one at the pond to sense water temperature to better care for my Koi during the winter months. I'm using an Ambient Weather WS-2000 weather station.
