It seems like you hear it every year — a late or early frost threatens some crop or another, forcing farmers to take drastic action to avoid financial ruin. But even when the weather cooperates on a large scale, microclimates can still cause big problems in small enough areas to go unnoticed until after the damage is done.
As always, better data can lead to better decisions, and increased granularity of environmental data could do wonders for certain kinds of agriculture. Enter SLoRa, a wireless weather station for agriculture. Aimed at providing a network of cheap, low-power temperature sensors, [Dorijan]’s proposed system would allow farmers to take active measures to protect their trees from frosts — smudge pots to heat the nascent fruit, sprinklers to apply a protective layer of ice, or even hovering helicopters to move massive amounts of warmer air into cold spots. With a solar powered sensor array and a LoRa link to a hilltop gateway, each SLoRa sensor deployed will be one more data point a farmer can use to determine where to deploy his or her limited resources.
