This time I get out my I Never Won A Blue Peter Badge badge, a stack of foam board, some sticky tape, more sticky tape, some hot glue, some recycled fabric insulation stuff from a dishwasher and knocked together a box for insulating the heat absorbing temp sensor. Not much really to say about the construction. I think the pictures say it all.
This is the end product and really does appear to work well. It managed to record a temperature of just above 70°C a few days ago. 😯 That's about 20°C more than before it was in the insulated box. It still needs some small tweaking as when I open my window the cool air comes in from outside and does cool the temp sensor a little. I plan on putting either a piece of glass or plastic (perspex/polycarbonate) over the front to stop the cooler air actually getting to the temp sensor. 70°C is pretty insane when you think about it. If I were to paint my arm with matt black paint and put it in direct sunlight, it would literally cook my arm. That's not something I will be trying! 😄
I have received some new sensors as mentioned in the previous update, but I haven't done anything with these yet. I'll look at them in due course. I am also considering relocating it somewhere where it gets more sun light, maybe south facing, that way it would record the light coming and going earlier in the day, peaking at lunch time. That's not so easily doable though and would probably have to be mounted on my house roof somewhere. I'll give it some thought. I have also improved the website a little. Made the graphs a little more colourful and added a page with live gauges for all for the sensors. Although I don't really like the highcharts gauges as they have too much text and stuff integrated into them. They look a bit too busy. It would also be nice to have them update properly without the page refreshing.
To do:
- Put a glass or plastic cover over the front of the solar heat sensor.
- Have a play about with the new sensors.
- Anything else I think of.
