Years of electrical, hardware, and software engineering has gone into the design and development of SKY to allow our precision sonic anemometer to operate on battery power alone. (Go ahead, do a google search for sonic anemometers – vast majority are wired and required external power.) No wires means better siting. Better siting means better data. In normal operating mode, SKY samples and reports the wind every 3seconds. With eight AA Lithium batteries, the power consumption curves should allow for 8-14 months continuous operation.
For those who want longer battery life, we’ve recently added the ability to toggle SKY into a power saving mode that samples and reports wind every 15seconds. This leads to roughly a 3 - 4X increase in expected battery life – which translates to 2yrs+ on a single set of AA batteries.
To enable power save mode:
