Introduction to the IoE Module
Welcome, and thank you for your purchase of the IoE (Internet of the Environment) Module. If you have just taken delivery of your order, check the packaging list to be sure you received everything that you ordered. The IoE Module may include some or all of the following components and services:
- Cellular service plan and access to LI-COR Cloud™ (1 year).
- Backup data logging to a removable Micro SD card (all configurations).
- Built-in charge controller for the solar power supply (all configurations).
- Solar and battery power supply (optional).
- Mounting structure and enclosure for sensors and equipment (optional).
The IoE Module powers sensors for continuous long-term operation, while simultaneously posting data to the LI-COR Cloud™ via a cellular network. It allows operators to view data and assess results from sensors without visiting the sites.

Enclosure and electronics
The enclosure houses the electronics, antennas, and other components.
Warning: Read and understand the operating instructions and safety information before using this equipment. Failure to understand the safety information may result in bodily injury, damage to equipment, or unsatisfactory results.
Components
Components of the enclosure are labeled and described below.
- Display: Monochrome display that presents status and configuration information. See The IoE module interface for a tour.
- Buttons: Buttons include power, navigation, select, and mount/unmount card.
- Battery Shelf: To support the optional battery. Always use the hold-down bracket when a battery is installed.
- Serial Number Label: The serial number label gives the product serial number, which may be useful if you need technical support.
- Micro USB Port: To connect to a computer for manual firmware updates. Accepts a Micro-B connector.
- Micro SD Card Slot: The slot is for the included Micro SD card to store a backup of data. An 8 GB card is included (part number 616-21301). The 8 GB card can store many years of data, typically. Most micro SD cards will work as long as there is ample free space for files. The FAT32 format is recommended.
- Battery Cable Connector: The cable from the optional 12-volt lead-acid battery attaches to this connector.
- Auxiliary Power Out: One auxiliary power supply is provided inside the enclosure. Contact LI-COR technical support if you want to use the power out.
External connectors
The external connectors are for sensors, auxiliary power, and solar panels.
Warning: Read and understand the operating instructions and safety information before using this equipment. Failure to understand the safety information may result in bodily injury, damage to equipment, or unsatisfactory results.
- SDI-12 Connectors: Two connectors for SDI-12 devices. Power, configuration, and data transfer are supported. The device must have a 5-pin sealed connector. The Stevens Soil Probe available from LI-COR (part number 900-19016) has the connector. The SDI-12 power supply provides 12 VDC with a maximum of 2.5 amps total, including the Sensor Connector.
- Sensor Connector: Accepts the LI-710 Evapotranspiration Sensor cable. It features a 5-pin sealed connector for a combined SDI-12/RS-232 port. The SDI-12 power supply provides 12 VDC with a maximum of 2.5 amps total, including the two SDI-12 connectors.
- Auxiliary Power Input: For operation from an external power supply (other than the solar panel or battery). Supports 9 to 33 VDC, 3.0 A maximum current.
- Solar Panel Inputs: To attach the solar panel extension cables. The maximum input is 9.15 A (circuitry is current limited to prevent damage). Compatible panels should output 17 to 21 V, with a maximum open circuit voltage of 32 V.
Warning: Do not connect solar panels with voltage rating that is higher than specified. Doing so can damage equipment or cause injury.
Compatible devices
The IoE Module supports the LI-710 Evapotranspiration Sensor and one Stevens Soil Probe. The devices are configured automatically, and data are delivered to the cloud storage repository or stored on the Micro SD card.
LI-710 Evapotranspiration Sensor
Part number LI-710
The LI-710 connects to the IoE Module with a double-terminated 5-meter cable (part number 392-20750, included with each IoE module). When paired with an IoE Module, it is a Water Node on LI-COR Cloud™. LI-710 firmware v1.0.8 or newer is required for compatibility with the IoE Module and LI-COR Cloud™.
Stevens HydraProbe
Part number 900-19016
The IoE Module supports a Stevens HydraProbe soil moisture (firmware v4 and above), temperature, and electrical conductivity probe with a connector-terminated cable.
Precautions
We recommend wearing sturdy work gloves during the installation and safety glasses when working with guy cables. Bring your favorite snack and some drinking water, and it'll be a good day!
Warning: Read all the instructions in this manual prior to assembling, moving, or disassembling the device.
