my ramblings......apologies for the sequence - they just came out my head that way....
from the posted diagram - why 2 boxes inside the house? combine? whats your thought process?
if we are using separate modules (nodes) for each sensor.....what sort of topography
for our "network"?
all reporting to one master? or all capable of acting as relays/extenders? (ie, they retransmit what they hear if the
msg is not for/from them)
what range? 50m 100m 300m 4000m? these are available radios in the 433mhz world. obviously they are all
"perfect clear line of site ratings" - so i guess we need to aim for the 300m one with the hope it will do half that??
the radios are available as receiver, transmitter or transceiver (can do both). the transceiver modules are a few
bucks more expensive - but make the network more flexible. plus i think that it will make life a hell of a lot easier
for network congestion - all radios might talk at once if they are not 2 way. we need them to talk only when
polled by id by the master?
i know some of you get scary cold temperatures.....what does it need to go down to?
the transmitter works within the range: -45C to 85C
i agree that the transceiver should be interchangeable - so they can easily be swapped out if necessary, or the sensor
changed.
heres the thing......how many people are going to be creating their weather station from the dream machine?
(i know you cant answer that) - but are they all going to be good at soldering? no. or loading code into
micro controllers? no.
do i want to do that for them? no. do you? i suspect not. - how are we gonna get these babies out to the people
who want to test them?
how much will people pay per node (excluding sensor?)
the cost adds up (even though individual components are quite cheap)
(pcb, battery, solar panel, atmega chip(not a full arduino - thats just for dev phase), radio, case, i/o connectors, capacitors,
resistors, diodes, leds (no doubt! bling!)
my current thinking is that personally i wont use a console. my inside master controller will be ethernet capable and will insert data onto
a database on a networked pc. on that pc will be a web server. i will access my data from a pc, smartphone or ipad.
lastly, you asked for arduino help. i can do that. i dont want to teach you to suck eggs like a total beginner,
unless thats what you (and the forum) would like? do you need specific help with code or circuits? or do we
want a 101 on what to buy, how to connect it - and then getting a temperature reading from a ds18b20, or a hih-4030
humidity sensor? let me know
sorry to add more questions to the project. feel free to ignore me if u feel they are the ramblings of an idiot
