  • Sensor can be completely mobile and mounted in any orientation
  • DIP switches allow sensor to be set for mode of operation to best match application
  • Reverse polarity protected to 50V
  • Current Drain 15 mA nominal. (No outputs on, not raining, no heater)
  • about 1.5 mA in micro-power sleep mode.
  • 50 mA with output on. 
  • Output Relay closure, Normally Open and Normally Closed contacts.
  • Max load 1A, 24 VDC. 

The SBKBRNO Rain Gauge is a maintenance-free optical rain sensor that can be used for a wide variety of rainfall monitoring and control applications. The Rain Gauge senses water hitting its outside surface using beams of light. The complete sensor package is about the size of a tennis ball and completely sealed from the environment.

The optical sensing technology overcomes many of the shortcomings of conventional tipping bucket rain gauges. The sensor works in mobile environments, there is no collecting funnel to clog with leaves, and the round shape makes it essentially self-cleaning. While the sensor is not as accurate as a tipping bucket rain gauge, the low cost and compact size of the SBKBRNO makes it ideal for wet weather notification systems or remote rain gauges where periodic maintenance is not possible.
