A battery-powered rainfall data collection and recording system that includes a HOBO Pendant Event data logger integrated into a tipping-bucket rain gauge.
A battery-powered rainfall data collection and recording system that includes a HOBO Pendant Event data logger integrated into a tipping-bucket rain gauge. This model automatically records up to 3200 mm of rainfall data, which can be used to determine rainfall rates, times, and duration. Also records temperature when used with an optional solar radiation shield (RS1 Solar Radiation Shield or M-RSA). A base station or shuttle is required.
In what environment does this data logger operate?
This data logger operates in an outdoor environment.
