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
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). 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)
Response Time: Airflow of 2 m/s (4.4 mph): 10 minutes, typical to 90%
Logger:
Time Accuracy: ±1 minute per month at 25°C (77°F)
Operating Range: -20° to 70°C (-4° to 158°F)
Battery: CR-2032 3V lithium battery; 1 year typical use; deployments in extremely cold or hot temperatures or logging intervals faster than one minute may significantly reduce battery life.
Memory: 64K bytes
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
What's In The Box
HOBO UA-003-64 Pendant Event Data Logger
Tie wraps
Adhesive mount
Measures rainfall to determine rainfall rates, times, and duration; for 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, which is only stored at the time of event, for better memory usage. For accurate temperature measurement in sunlight, a solar radiation shield is required (assembly-required RS1 Solar Radiation Shield or pre-assembled M-RSA Solar Radiation Shield).
