Descripción
Accurately measure rainfall with the HOBO Pendant Event Data Logger. Determine rainfall rates, times, and duration after deployment with most standard tipping-bucket rain gauges. Efficiently gather and store momentary contact events and temperature data. Additionally, gain access to detailed event data. Event data is only stored when it happens for better memory usage. Use a solar radiation shield for accurate temperature measurement in sunlight applications. See RS1 Solar Radiation Shield (assembly required) and M-RSA (pre-assembled) Solar Radiation Shield.
Environment:
The UA-003-64 Data Logger is for use in Indoor and Outdoor environments.
Measurements:
The UA-003-64 Data Logger supports the following measurements:Temperature, Event, Rainfall.
Manufacturer Specs
| External event input | |
| Event sensor | Two-wire interface suitable for measuring mechanical and electrical contact closures |
| Maximum input frequency | 1 Hz (1 pulse per second) |
| Lockout time | 500 ms |
| Minimum pulse width | 1 ms (hardware debounce) |
| Input/output impedance | 100 kO |
| Edge detection | Falling edge, contact closure, or Schmitt-trigger buffer |
| Preferred switch type | Normally open. For maximum battery life, the event input should be used with its preferred switch type. The logger will work with normally closed switches, but battery life will be compromised. |
