The HOBO Pendant Event data logger is ideal for rainfall logging and connects to most standard tipping-bucket rain gauges to determine rainfall rates, times, and duration.
Features
Applications
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 kOhm |
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 (-) |
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% |
