Overview

Optical Interface for data transferAccurately 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.

Externally Mounted pendant event logger

Highlighted Features

  • Ideal for recording rainfall with tipping-bucket rain gauges
  • Records tips or momentary contact closures 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 (-)

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
