The Green House Effect (damn hot!)

The greenhouse effect is something you can observe experimentally - and most people have observed the greenhouse effect themselves, in greenhouses.
Nicholas Stern

Those paying close attention to the IOT temp/humidity data would have been somewhat alarmed by the past 24 hours of readings.  Firstly they were intermittent; and secondly was it really 47 degrees Celsius in the mountains of Tasmania today?

Dubai or Tassie?
The reason for this alarming and intermittent spike is the relocation of the electrickery box to the green house.  Apart from the longer distance for the WiFi connection, now about 25 m and through 7 walls, it gets damn hot in there (and dry - the humidity is very low in that heat).  So there are some challenges ahead.

1. Clean out all the old stuff and refit

Chop, hack and dig...
2. Hook up the green house to monitoring, the new external antenna should help with the consistency of connection (plus some recent hacking of the code), and we've got some more powerful ESP8266 modules winging their way from 中国

Little house...little antenna...
3. Collect data and figure out what we are dealing with in terms of the localised environmental conditions

One day I'll ditch the lunchbox...tacky!
4. Hook up devices to react to the monitoring, either delivering water (spray or drip), opening louvres, heating, cooling, etc., all powered either by a robot monkey or more likely a few solar panels and some 12 V batteries.

It's the TARDIS!
OK so maybe it won't look like the picture above - but it's nice to dream, eh?  In the meantime for those wishing to see what the greenhouse effect is all about, go get yourselves a glass box and enjoy some elementary science.

How the effects of anthropogenic gases have become a benchmark of political stupidity here in Australia is perhaps an exercise best left to the misanthropic!  47 degrees in Tasmania!  It's a scandal!
