Outdoor Rainfall Pulse Data Recorder Company

HOBO Rainfall Pulse Data RecorderUA-003-64 measures rainfall to determine rainfall rate, rainfall duration, and duration; Used for deployment with most standard tipping bucket rain gauges.

feature

• Very suitable for using a tipping bucket rain gauge to record rainfall

• Record instantaneous contact closure and temperature

• Pulse signal based data storage provides detailed data and efficient memory usage

• Store over 16000 suction heads (160 inches of rainfall, 0.01 inches of rain gauge)

• Including scaling in inches, millimeters, or other units

Specifications:

External event input
Event sensor:Dual line interface, suitable for measuring mechanical and electrical contact closure
Input frequency:1 Hz (1 pulse per second)
Lock time:500 ms
Minimum pulse width:1 ms (hardware debounce)
Input/output impedance:100 kΩ
Edge detection:Falling edge, contact closure or Schmitt trigger buffering
Switch type:Always open. To achieve the longest battery life, the event input should be used in conjunction with its switch type. The recorder will be used with a normally closed switch, but the battery life will be affected.

Open circuit input voltage stage:Battery voltage; Nominal 3.0 V
Input voltage:Battery voltage+0.3 V
User Connection:24 AWG， 2 leads: white (+), black (-)

temperature measurement
Measuring range-20 ° to 70 ° C (-4 ° to 158 ° F)
Accuracy:0 ° to 50 ° C ± 0.53 ° C (32 ° to 122 ° F ± 0.95 ° F), as shown in Figure A. Accurate temperature measurement under sunlight requires a solar radiation shield.
Resolution:0.14 ° C at 25 ° C (0.25 ° F at 77 ° F), as shown in Figure A
Drift:Less than 0.1 ° C/year (0.2 ° F/year)
Response time:Airflow of 2 meters per second (4.4 miles per hour): 10 minutes, typical value of 90%

record
