OVERVIEW
Discover Hidden Energy Inefficiencies and Improve Performance
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.
Features- 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
Important Information
External sensors sold separately. Requires HOBOware software .

(Optional AA lithium batteries available for operating conditions of -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 (0 to 2 seconds for the first data point and ±5 seconds per week at 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 -

HOBOWARE SOFTWARE
HOBOware Software
HOBOware software is used for launching, reading out, and plotting data from HOBO® data loggers. With HOBOware, you can also check logger status, filter and export data, save changes to graphs in project files, and scale data with the Linear Scaling and Pulse Scaling data assistants. There are two versions of HOBOware: HOBOware and HOBOware Pro.

TECH NOTES & WIRING
Tech Notes and Wiring Diagrams
Wiring Diagram – Monitoring DC Voltage and Current with the H22-001 Energy Logger
Linked is a drawing that shows how to monitor DC voltage and/or current using the H22-001 Energy Logger via the S-FS-CVIA Analog Module. For DC current monitoring, the T-VER-H971BP-200 DC Current Transducer is needed also.
Wiring Diagram – Monitoring 480V, 3-Phase AC Voltage and Current with a HOBO H22-001 Energy Logger
Linked is a wiring diagram that shows how to use CTs and PTs with the HOBO H22-001 Energy Logger via the S-FS-TRMSA Module. The image shows a 480 V, 3-phase application. The configuration would be similar for single- or split-phase applications.
Wiring Diagram – HOBO H22-001-S-FS-CVIA Voltage Input Logic Switch
Linked is a wiring diagram that shows how to monitor switch closures with a HOBO H22-001 Energy Logger fitted with the optional 2-channel analog input module S-FS-CVIA
Verifying RH accuracy on HOBO data loggers
Testing the accuracy of relative humidity sensors requires carefully-controlled conditions and a considerable amount of time. Please see the linked white paper Testing the Accuracy of Sensirion Relative Humidity Sensors in HOBO Data Loggers for complete details on the recommended procedure to follow.
Smart Sensor Sampling Interval
When a sampling interval is configured, the station or logger will take multiple measurements within a given logging interval and then average them together to create a single logged data point.
Smart sensor cable fix
Problem: My smart sensor data shows a -888.888 for a good portion of the data file. Note: -888.888 means that the logger could not find the smart sensor after the logger was launched successfully.
Sample Data – Missing Smart Sensor -888.88 Error
Linked is a screenshot that shows the HOBOware error values displayed when a smart sensor is disconnected from a smart sensor-compatible logger, specifically the HOBO H21-002, U30, and H22-001.
Sample Data – HOBO U30 Station Monitoring Soil Moisture, Leaf Wetness, and Soil Temperature on a Green Roof
Linked is a screenshot from a HOBOware data file recorded by a HOBO U30 Station that recorded soil moisture, leaf wetness, and soil temperature as part of a green roof project.

Troubleshooting for Rapid Battery Consumption (outdoor loggers)
Protecting data loggers from electrical discharge (ESD)
A discharge of static electricity may cause a running data logger to stop recording.
Possibility of exposure to chemicals or chemical vapors
This is dependent on the data logger you are using and the chemical and/or concentration of the chemical to which the data logger is exposed.
Maximum sensor cable length
The entire network (all sensors combined) cannot exceed 100 meters. As long as your total cable length is below this, it does not matter how you designate the individual cable lengths. It is important to insure that the connections are weatherproof.
Logging Duration in the Launch Screen – What Does That Mean?
In the HOBOware and HOBOmobile Launch screens there is a number that is presented as “Logging Duration”. This number is not how long the battery will last!

Data loss and recovery
There are two common reasons for data loss
Data logger is shutting off prematurely
A discharge of static electricity may cause a running data logger to stop recording. Precautions should be taken to prevent this while handling the data logger. Discharges may occur when there is a charge difference between the data logger and a cable being connected to it or when a person touches an exposed jack.
