    SOLAR POWERED ARDUINO WEATHER STATION

    Using 2x AA NiMh batteries with a dc-dc booster you say to "Solder the '+' terminal of boost converter to the battery positive terminal.Solder the '-' terminal of the boost converter to the battery negative terminal."But where do i solder on the solar panel? in parallell to the battery? if my solar panel can produce 6v in peak conditions how will the booster that can take 0.9v-5v handle that?Or should i skipp the booster and use a arduino pro mini (3.3v) version and connect the solar/battery to the vin pin (the one with the built-in voltage regulator)?Another note: i'm planning on using the solar powerd arduino to run a waterpump to water the flowers rather than for sensors.It will be in sleep and waking up about every 3 hours and checking if its light or dark out, if it's dar...see more »Using 2x AA NiMh batteries with a dc-dc booster you say to "Solder the '+' terminal of boost converter to the battery positive terminal.Solder the '-' terminal of the boost converter to the battery negative terminal."But where do i solder on the solar panel? in parallell to the battery? if my solar panel can produce 6v in peak conditions how will the booster that can take 0.9v-5v handle that?Or should i skipp the booster and use a arduino pro mini (3.3v) version and connect the solar/battery to the vin pin (the one with the built-in voltage regulator)?Another note: i'm planning on using the solar powerd arduino to run a waterpump to water the flowers rather than for sensors.It will be in sleep and waking up about every 3 hours and checking if its light or dark out, if it's dark it will check for soil moisture and then if needed start the pump for ~10 seconds.do you think this rig will be able to run like this or will i need to add more batteries and solar panels for it?
