Overview
Record up to 160 in. of rainfall at rates up to 12.7 cm (5 in.) per hour. The Data Logging Rain Gauge system is battery-powered and includes a HOBO Pendant Event data logger with a tipping-bucket rain gauge. Easily collect rainfall, time, and duration data, as well as temperature, when used with an optional solar radiation shield (RS1 Solar Radiation Shield, or M-RSA). A base station or shuttle is required.

  • Tipping-bucket rainfall collector
  • HOBO Pendant Event Logger
  • Mounting accessories: two hose clamps, three screws
Questions & Answers
How do these sensors log data, do I need an external device?
The Onset data-logging rain gauges record tipping bucket events with an internal HOBO pendant event logger.
Can temperature be measured with the Onset data logging Rain gauge?
Air temperature can be collected along with rain data by routing the HOBO pendant temperature and event logger outside the tipping bucket and mounting the logger in a solar radiation shield.

Wildfire Prevention in the Sierra Nevada Region with the Yuba Watershed Institute

Though recent wildfires have sparked new conversations about wildfire management and response, groups like the Yuba Watershed Institute have been monitoring the forests and water resources of the Sierra Nevada region for decades, managing approximately 5,000 acres of land with the Bureau of Land Management (BLM) and about 7,000 acres in private land partnerships. The goal of the Institute is to work with local communities and land agencies to improve watershed and forestry management through informed practices and public outreach. The goals of the Yuba Watershed Institute are three-fold: Improve the ability of fire suppression agencies like the California Department of Forestry and Fire Protection ( CAL FIRE ) and the US Forest Service.

Wave Sensors Integration with NexSens Buoys: A Cutting-Edge Solution for Wave Measurment

Real-time wave data supports accurate weather prediction, safe and efficient maritime operations, and provides valuable safety and operating condition information for recreation and commercial fishing. Understanding wave dynamics also helps with the design of protective coastal structures like seawalls, breakwaters, and jetties. It also supports better prediction of their impact on sediment transport and coastal geomorphology. Wave data is a key factor in qualifying and designing offshore wind farms and harnessing kinetic energy for electrical generation. It helps with the understanding of ocean-atmosphere interactions and contributes to studies of sea-level rise and climate change impacts.
