3D model description

This is my design for Arduino Uno together with LCD Shield and attached DHT22 Temperature Humidity sensor module. While designing the box, I try to have as small size as possible. To make it compact, the sensor is placed at the back of the case. However, this created a downside. Because of being too close to the circuits, sensor receives some heat from electronics inside the box. In my case, I have observed ca. +4 deg C temperature increase after installing in place. You might want to consider this point and it might be good idea to get the sensor completely out of the case. A tiny enclosure can be made separately for the sensor itself and be placed a bit far from the main circuit to have more accurate measurements. I am powering this with ordinary 9V adapter. All bolts and nuts are M3 (Metric 3) size and their length are 16mm.
There exist two holes (4mm dia.) in front of the box for "Select" and "Reset" buttons underneath. You can design buttons for these as you wish or left as they are to be used with a pointed object when needed.
Moreover, If you curious about the calibration and precision about humidity sensors, you may have a look at
