[Wireless Room Temperature Monitoring System] 3D Printed enclosure final result !

After so many weeks of inactivy (I have very good reasons i promise) i finally had the time to finish the CAD file for the enclosure and to get it printed at my local store in Alsace :)

Here is the final result. It is far from perfect unfortunately. I didnt plan for the support to get merged with some of the structure i designed. Also some of the structure were too small and had small hanging part, under which support material was still put and unfortunately ... i had to cut the whole thing to make it work. Here are a few thing that i would do differently next time :

On the left, i was too optimistic to have the small bump to guide the arduino mini pro ... unfortunately since there was hanging part over it, the bumps got merged with the support material ... i ended up remove the whole top part. Same issue with the one in the middle ... the support material added by the 3D printing software screwed the print. On the right, i made a different mistake to put the screwing hole for the temperature sensor above a another guide... i didnt plan for the support material for the screwing hole to merge with the structure below ...

Here are the pictures of the final result ! Let me know your thoughts or suggestions !

Now that the components are all designed in 3D i can try an design the enclosure.

I tried to take into account the way the elements are going together, how the cables are connecting the components and all. I am not even sure this could be 3D printed. Here is what i intend to send for printing :

What do you think ? Any suggestions ?

[Wireless Room Temperature Monitoring System] Enclosure for wireless temperature sensor 3D Modeling with 123D Design

Alright so now that i have a rough idea of how the enclosure should be i can go ahead and design it in CAD. 123D Design seems perfect and easy to use. As a training exercice I decided to reproduce all the components that are involved in my sensor in 123D Design at the exact correct scale. This way i will be able to design the enclosure to take into account. First i took exact measurement of each of the 5 main components that are involved in the sensor.

Here is how it looks :

Here is a picture of the real stuff :)

What do you think ?  Any advice ?

If anyone is interested for their own CAD design (and if you use the same components as me ...) please contact me and i will give you the .stl file

Next, i will make the enclosure using those components to make sure that everything fits together

[Wireless Room Temperature Monitoring System] Enclosure for wireless temperature sensor prototype

Alright, so now that i have to mess up with the code and make the code work properly, i need to have an easy to handle hardware prototype. To do so i incorporated a switch so i can put the sensor on and off without having to unplug the battery.

There it is :  The switch is available on the front side. I made a hole to have the temperature sensor stick out of the box for more accuracy.

View of the inside... pretty messy but it works

And there it is closed, the antenna is sticking out of the box through  a hole.

Until I design a 3D printed enclosure, that will do the trick. 

[Wireless Room Temperature Monitoring System] Sensor Enclosure Prototyping Part 1

I have been doing some thinking on the enclosure i want to 3D Print myself.

The goal is to have a relatively simple design to store all modules : Arduino, Temperature sensor, 9V Battery enclosure and TX RF 433 Mhz Module.

Here are the first prototype drawings :

 

I am already having second thoughts about the enclosure, specifically about the antenna. My latest test showed that i should have a linear antenna instead of a coiled one...

I will have some more drawing done in the following days.
