Hobo H22 Energy Data Logger

  • Vendor:Onset

Availability: Available Item


This 15-channel data logger lets energy and facility managers monitor energy and industrial equipment to quickly and easily detect and address a variety of issues relating to HVAC, machinery, and other systems. A modular device, the HOBO H22-001 Energy Data Logger is more economical than its alternatives because it eliminates the need for a toolbox full of data loggers.

Deploying this logger with a variety of pre-defined plug-and-play smart sensors create a robust monitoring system, and it's compatible with HOBOware software, so researchers can conduct effective data analysis in minutes.


  • Flexible data logger records up to 15 channels of more than a dozen measurements
  • Provides 12v excitation for third-party sensors
  • Pre-configured Smart Sensors get you started fast
  • Signal conditioning modules retain configurations until you change them, providing plug-and-play convenience for commonly used sensors
  • Flexible power options include battery operation for AC power adapter
Operating range -20° to 50°C with alkaline batteries -4° to 122°F with alkaline batteries   -40° to 60°C with lithium batteries -40° to 140°F with lithium batteries
Sensor inputs Three FlexSmart multi-channel modules and up to 6 Smart Sensors (which may have multiple parameters/channels)
Sensor connectors Six RJ-12 Smart Sensor jacks plus 3 FlexSmart module slots
Communication RS-232 via 3.5 mm serial port or/and 9-pin D-Sub connector
Dimensions 15.6 cm x 8.4 cm x 4.6 cm 6.13" x 3.31" x 1.81"
Weight 435 g with batteries 15.23 oz with batteries   238 g without batteries 8.33 oz without batteries
Memory 512K nonvolatile flash data storage
Memory modes Stop when full; wrap when full
Operational indicators Six indicators provide logging and sensor network status
Logging interval One second to 18 hours, user-specified interval (2-second minimum for two-channel S-FS-TRMSA operation)
Sensor excitation 12 V DC at 200 mA total, with user-programmable warmup time on a per-channel basis
Battery life One year typical use (up to 75 mA excitation with 10-minute or longer logging Interval and 1-second warmup time)
Battery type Eight standard AA alkaline batteries for operating conditions -20°C to 50°C (-4°F to 122°F) Optional AA lithium batteries for operating conditions of -40° to 60°C (-40° to 140°F)
External power Supports optional 13.6 V DC regulated AC Wall Adapter Connector. Internal batteries may remain installed. Alternatively, an automotive battery or 9-12 V DC regulated Wall Adapter may be used, but it is recommended to remove the internal batteries since they will discharge to the level of the external supply.
Time accuracy 0 to 2 seconds for the first data point and ±5 seconds per week at 25°C (77°F)
Logging mode Immediate, timed delay, or trigger (button-push) start options; supports sampling intervals for some sensors
Data communication Current readings while logging; read out while logging; read out when stopped
