The HOBO Pendant Event economic Data Logger UA-003-64 is ideal for rainfall logging and connects to most standard tipping-bucket rain gauges to determine rainfall rates, times, and duration. The HOBO Pendant Event records momentary contact events and temperature. Event data is only stored when it happens, which results in efficient memory usage while still providing detailed event data.

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

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: ± 0.47°C at 25°C (± 0.85°F at 77°F), see Plot A. A solar radiation shield is required for accurate temperature measurements in sunlight.

Resolution: 0.10°C at 25°C (0.18°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: ± 1 minute per month at 25°C (77°F), see Plot B

Operating range: -20° to 70°C (-4° to 158°F)

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
