Kyneton gets cold...very cold.
In an effort to quantify just how cold it gets, I decided to set myself a little project where I created my own weather station using:
Simply, the project does the following:
To house the sensors, I've used a spare toolbox I had lying around. I left the Pi inside another plastic box to stop dew forming on it and shorting the electrics. To make sure that the sensor readings were as accurate as possible I drilled a few holes into the side of the case. This lets it breath but also keeps a few compartments distance between the atmosphere and the computer and battery.
Initially I intended to power this set up via solar. The solar would feed the battery, and the battery would then feed the raspberry pi, but I’m reluctant to leave the solar panels outside in the elements (ironic) so I might find a way to either move the pi into a shed (where I can connect it to mains power) or integrated it into the garden lighting system I have (although this would use significantly more electricity as the 230W transformer I have for my garden lights would need to be on the whole time.
Next up I plan to make this tweet out the temperature at it's coldest point each morning - a sort of sadistic town crier for the freezing souls getting out of bed and heading to work each morning.
