I have finally finished stage one of my revamped weather station.
This includes a remake to the original radiation shield, made out of 11 melamine dishes (it's missing the top and bottom plates in the pic.s) and now with a 24/24h running fan aspiring a 6cm diameter PVC tube housing the temp/hum sensor. I tried keeping the light/radiation out by using a telescope like dampening system where the air enters laterally facing a ring.
There should be enough space around the PVC tube to let air flow naturally as well.
Below is the TX Box. The fan is actually being powered by a 12v car adapter I had unused. The sole bonus being I can actually control the speed by adjusting the voltage anywhere from 1,5v to 12v.
The ON/OFF switch is a bit of an overkill but again, I am reusing an available part. The capacitor is there for no plausible reason, except in the past I found it helped even a crippled regulator and I just thought it might be a good idea.
The system is solar powered using a 85W panel coupled with an 150AH lead acid battery. Both reused.
The regulator (below) powers both the TX unit, the FARS and the RX Unit. In the future it should also power a second TX unit.
To be done:
On the software side: I found the custom Debian kernel on the NAS I am planning to use to transmit data to the Internet is missing the required ch341.ko driver so as to communicate over usbserial with WeatherDuino. I risk to have to recompile the damn thing myself.
On the hardware side: completing the UV/Solar radiation portion and building a second TX Unit which, unlike the first one, which is up in the roof, should be placed in the ground.
