Overview
Connects sensors with pulse outputs to data loggers with smart-sensor inputs. Compatible with contact closures, such as tipping-bucket rain gauges or reed switches with a maximum input frequency of 2 Hz (2 pulses per second), and a preferred switch-type of normally-open. See how the pulse recorder works.
