OVERVIEW
Easy to add to HOBO loggers and stations
The Contact Closure Pulse Input Adaptor connects sensors with pulse outputs to loggers with smart-sensor inputs. This smart sensor is 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
The pulse input adapters are used to log the number of switch closures per interval and are designed to work with smart sensor-compatible HOBO® loggers and stations. The adapter has a plug-in modular connector that allows it to be added easily to these devices.
Features
- Plug-n-play adapter for pulse output sensors
- Automatically recognized by H21, H22, U30, and ZW data loggers
- 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)
