The response time and accuracy of this board are excellent. About a second of response time, and 1.8% RH accuracy make this device ridiculously useful for filament storage and other applications. We are minimally marking it up as a service to our community. You can order the full-up sensor and case (designed by us), or just the case if you already have the Sensirion board.

If you want the board, case, AND bracket, make sure you pick the EVERYTHING option.

The sensor on the board is the Sensirion SHT40. Here is the DATASHEET from them.

The STL files to print your own case are available from our LINKS page.

You can order the Sensirion Board from DigiKey (1649-SHT4XSMARTGADGET-ND), details also on our LINKS page.
