Need some technical informations and advices.
hello everyone;
like said in last topic: http://forum.arduino.cc/index.php?topic=240124.0
i'm working on road traffic monitoring project. need technical informations , advices.
first of all, start explaining how project work. want set arduino uno borads (equiped ir , ulrtasonic sensors) should send number of cars counted every minute (with zigbee) server (for data processing).
the probem sending data every minute rapidly decrease bettery level, thougt use solar cells have lot of sun here in country. other thing i've thinked programe arduino board not send data when traffic stoped or number of cars counted not significant , put in sleep mode when road traffic reduiced (e.g. night).
my qustions :
how minimum energy arduino need work corectly (in case) ?
what kind of battery should use , how power ?
what dimessions of solar cells should use energy board need. ? (i live in hot country, sun not problem).
if it's possible (approximative values good), give me energy consumption of arduino operations (sending data, converting signals, processing, ...).
if have advices or suggegtion, verry helpful.
thank in advance.

the energy requirements of arduino quite variable based on doing. if doing lot of analog reads , doing constant computations may take lot more power if doing , placing chip in low-power sleep mode.
odds larger power draws sensors , particularly wireless radio. draw of these entirely dependent on type , brand of sensor , how using it.
if me, build device , use bench-top power supply or meter measure current consumption. can go sizing battery , solar panel.
as far battery might sealed lead acid (sla) battery, meant quite hassle free , can find solar panels , chargers go along them easily. as far solar panel area, depend on technology used in panel, instead 1 has needed wattage. if panel won't tell wattage, don't want it.
