A bit of background. We are located in Hawaii on the Big Island. In the area we wish to monitor, the temperature will not get below 50 degrees F nor go much above 85 degrees F. We won’t have snow in the area we are monitoring either. (I know, but such is life near the tropics). What we DO have are micro-climates where the weather can be quite different a few miles away.
We have a road going from a lower elevation of 2,000 feet up the mountain about 2 miles, ending about 3,500 feet altitude. We want to place a weather station at the low end of the road and then 3 more spaced out going up the mountain; each unit progressively further away. The units need to measure typical data like barometric pressure, humidity, wind speed, direction, rainfall, sunlight, solar flux, UV and so on. Since this is a farm, things like soil moisture and so on would be nice.
If there is a problem we can visit a remote unit to grab data, but really want to collect all data at the lower unit where we have a building with electric and internet. The other 3 units will be spread out up the road. They will not have electric nor internet and will probably have to communicate via cellphone because of the distance. We prefer not to run internet or power up the road. The only reliable cellphone provider in that area is Verizon and there is a cell tower near the building.
We will need to extract data to be sent to various people to review. We will probably also submit to Wundergound.
In this case, the cost is not the deciding item, unless it is exorbitant.
Does anyone have a suggestion?
