Power Consumption
Wireless Display: 2 x AA batteries (not included), we suggest Energizer Lithium batteries
- Expected battery life without optional AC adapter using Wi-Fi upload to AW.net is 5-6 months (the limiting
factor will be the amount of use of the backlight)
- Expected battery life using the optional AC adapter is 12-18 months
Sensor Array: 2 x AA batteries (not included), we suggest Energizer Lithium batteries
- Expected battery life: Energizer Lithium up to 2 years, Alkaline batteries at least 12 months, most rechargeable
batteries expect 12 months or less
14. Maintenance
1.
Clean the rain gauge once every 3 months. Rotate the funnel counterclockwise and lift to expose the rain gauge
mechanism, and clean with a damp cloth. Remove any dirt, debris, and insects. If bug infestation is an issue, spray the
array lightly with insecticide.
2.
When replacing the batteries, apply a corrosion preventive compound on the battery terminals, available at Amazon
and most hardware stores.
3.
In snowy environments, spray the top of the weather station with anti-icing silicon spray to prevent snow build up.
