Overview


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.

Highlighted Features

  • Ideal for recording rainfall with tipping-bucket rain gauges
  • Records tips or momentary contact closures and temperature
  • Event-based data storage provides detailed data and efficient memory usage
  • Stores over 16,000 tips (160 in. of rainfall with a 0.01 in. rain gauge)
  • Includes scaling to inches, millimeters or other units

For a self-contained rainfall logger, see the HOBO RG3 which includes a data logger integrated into a tipping-bucket rain gauge.

In what environment does this data logger operate?

This data logger operates in indoor and outdoor environments.

What measurements does this data logger support?

The UA-003-64 data logger supports the following measurements: Event, Rainfall and Temperature

 

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 kΩ
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.
Open circuit input voltage: Battery voltage; nominally 3.0 V
Maximum input voltage: Battery voltage + 0.3 V
User connection: 24 AWG, 2 leads: white (+), black (-)
Temperature Measurement
Measurement range: -20° to 70°C (-4° to 158°F)
Accuracy: ± 0.53°C from 0° to 50°C (± 0.95°F from 32° to 122°F), see Plot A. A solar radiation shield is required for accurate temperature measurements in sunlight.
Resolution: 0.14°C at 25°C (0.25°F at 77°F), see Plot A
Drift: Less than 0.1°C/year (0.2°F/year)
Response time: Airflow of 2 m/s (4.4 mph): 10 minutes, typical to 90%
Logger
Time accuracy: -20° to 70°C (-4° to 158°F), see Plot B
Environmental rating: Tested to NEMA 6 and IP67; suitable for deployment outdoors
Drop specification: 1.5 m (5 ft) onto concrete
NIST traceable certification: Available for temperature only at additional charge; temperature range -20° to 70°C (-4° to 158°F)
Battery: CR-2032 3V lithium battery; 1 year typical use
Memory: 64K bytes
Materials: Polypropylene case; stainless steel screws; Buna-N o-ring; PVC cable insulation
Weight: 50 g (1.7 oz.)
Dimensions: 71 x 33 x 23 mm (2.8 x 1.3 x 0.9 inches); 1.8 m (6 ft) cable
The CE Marking identifies this product as complying with the relevant directives in the European Union (EU).
