HOBO Event Logger


The HOBO Event Logger records the opening of a closed circuit and is used primarily for tipping rain collectors and industrial counting application. The event logger will record 8,000 events and store the time and date of each one. Only one time per event is stored to minimize memory usage for applications where the event duration is not needed.

Included with Event Data Logger

>> Weatherproof Case
>> 6 foot Cable

Required Software

>> BoxCar Software Kit

NOTE: Large Quantity Discounts Are Availabe!

Event Data Logger Applications

  • Industrial counting
  • Rain gauges / collectors
  • Turnstiles
  • Fixed-cycle machine usage

HOBO Event and Rainfall Logging

 The HOBO Event data logger can connect to standard tipping-bucket rain collectors to determine rainfall rates, times and duration. The HOBO Event Data Logger eliminates the need to manually read rain gauges, saving time and insuring that critical readings are not missed. Use it to upgrade existing tipping-bucket systems by replacing counting-type displays. We also offer atipping-bucket rain gauge that is packaged with the Hobo Event.

Features for rainfall measurement

  • Easily connects to 2-wire output or 2-screw terminals in the collector
  • Compact, weatherproof case can be mounted inside or outside the rain collector (avoid direct sunlight)
  • 8,000-tip capacity for up to 80" of rainfall between readouts with 0.01" tipping-bucket collectors
  • User-entered resolution to match with rain-gauge collector
  • Programmable lockout time to filter out false counts due to tipping-bucket bounce
  • Tip counts logged with time information to enable rainfall intensity determination
