Sensor Configuration

Sensor Setup for {{device_name}}

{{company_name}}’s {{device_name}} is a modular field datalogger designed to support a wide range of industrial and environmental sensors. It uses channels to logically connect sensor inputs to configuration and data collection rules. Each sensor input is connected to a physical pin, assigned to a channel, and managed through the {{platform_name}} interface.

Key Concepts

What is a Channel?

A channel represents one logical connection to a sensor. Channels are created and configured in the {{platform_name}} interface and mapped to physical or protocol-based inputs on the {{device_name}}.

Each channel includes:

  • A defined sensor type (analog, digital, serial, etc.)

  • Association with a SampleGroup for synchronized sampling

  • Display and data processing settings (e.g., scaling, units, alarms), managed on the {{platform_name}}

Channels abstract the raw physical wiring — you assign configuration to logical points rather than pin numbers directly.

Supported Sensor Interfaces

Sensor Type
Supported Inputs
Notes

Analog Current

4–20 mA

Most common industrial signal. Requires scaling setup in platform.

Analog Voltage

0–5V, 0–10V

Ensure voltage is within safe input range.

Digital Pulse

Pulse input

For flow meters, rain gauges, tipping buckets

Serial (RS485/232)

SDI-12, Modbus RTU/ASCII

Requires protocol-specific config in platform

Frequency & Periodic

FREQ, PCNT, PERIODIC

Used for pulse or frequency-based sensors

Virtual Channels

Calculated from other data

Power voltage, flags, totals, etc.

Device Modules

Depending on your {{device_name}} model, different input modules are available:

  • Analog Module – for current or voltage inputs

  • Serial Module – for Modbus or SDI-12 devices

  • Digital Input Module – for pulse, frequency, and event detection

Each module exposes labeled pins on the physical connector. Wiring is based on sensor type.

Steps for Setting Up a Sensor

  1. Identify Sensor Type Check your sensor’s datasheet to confirm if it's analog (4–20 mA, voltage), serial (Modbus, SDI-12), or digital (pulse/frequency).

  2. Wire the Sensor to the {{device_name}} Use the correct pin numbers based on your model and sensor type:

    • Signal (e.g., 4–20 mA) → Pin 1

    • Power (typically 12V) → Pin 3

    • Ground → Pin 8

  3. Create and Configure a Channel in {{platform_name}}

    • Go to the Device > Configuration tab

    • Add or edit a channel

    • Select the sensor type and input mode

    • Assign the channel to an appropriate SampleGroup

    • Apply scaling, units, and threshold settings

  4. Save and Sync Save your changes. The new configuration will be applied at the next transmission or manually via {{mobile_app}}.

  5. Verify Operation Use the {{platform_name}} dashboard or {{mobile_app}} to confirm that data is being sampled and reported correctly.

Tips & Considerations

  • Group sensors of the same type (e.g., analog current) into one SampleGroup

  • Ensure external sensors don't exceed device power limits if powered internally

  • Use diagnostics in the {{mobile_app}} to verify signal and operation

Device Replacement

“Device Replacement” is a functionality that enables switching a faulty Data Logger device with another Data Logger device without interrupting the continuous data flow. The data streams associated with the faulty device will begin receiving data from the replacement (new) Data Logger device.

Note: This process is specifically designed for cases where units are being replaced with identical models.

To enable Device Replacement, please contact support.

Eligible User Roles

This functionality is available to users with the following roles:

  • Account Owner

  • Partner

  • Distributor

Steps to Replace the Unit

  1. Go to the Fleet Management page of the platform.

  2. Enter the Serial Number of the Data Logger that is to be replaced.

  3. Mark the checkbox.

  4. Click Set Action > Device Replacement.

Device Replacement 1

  1. Enter the Serial Number of the new Data Logger that will replace the original unit.

  2. Mark the checkbox of the new device.

  3. Click Next.

Configuration Options

Choose one of the following:

  • Keep new device configuration – if the new device already has the required configuration.

  • Override with current device configuration – applies the configuration from the original device.

Note: The "Override with current device configuration" option is available only if both devices are of the same model and firmware version.

Device Replacement 1

Final Steps

  1. The system will verify device compatibility. Once verified, click Next.

  2. The system will attempt to map the data streams automatically. You may also adjust the suggested mappings.

  3. Define the field “Transfer data history from” to specify the start date for continued data flow.

  4. Verify the selected data.

  5. Click Submit.

The historical data will be moved as “Final Values” only.
