The HOBO Pendant Event/Temp Data Logger is a rugged, weatherproof event logger with a 10-
bit temperature sensor. It is ideal for use with tipping-bucket rain gauges, and can record tens
of thousands of measurements and events. The logger uses a coupler and optical base station
with USB interface for launching and data readout by a computer.
Specifications
External Event Input
Event Sensor Two-wire interface suitable for measuring mechanical and electrical contact
closures
Maximum Input 1 Hz (1 pulse per second)
Frequency
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 Battery voltage; nominally 3.0 V
Voltage
Maximum Input Voltage Battery voltage + 0.3 V
