G2-RAIN Logger Diagnostic Readings


All G2-RAIN data loggers have an internal set of sensors that measure important factors of system health. A total of (10) G2-RAIN Meta Parameters are collected.

 

  1. Cell Module Power

An adequate voltage supply is necessary to turn on the G2-RAINs cell module for data transmission to WQData LIVE. Values at or slightly above 5V are necessary to power the cell module.

 


  1. Processor Power

The 3.3V nominal regulated supply power being fed to the G2’s CPU and other internal components. Typically ranges between 3.2-3.5V.

 


  1. Input Power

Each G2-RAIN has the option of two independent power inputs. The voltages produced by these power supplies will represent the Input Power.

  1. NexSens G2-RAIN Battery Pack
    • Input power above 6.1 V are expected and adequate.
    • Input power below 6 V displays an imminent voltage decline and will require a battery replacement.
  2. NexSens SP-Series Solar Power Packs
    • Typical range is 12-15V

 

 


 

  1. Processor Current

The total power consumption of the processor within the system is monitored by the G2-RAIN.

It is best to disregard the status icon designation for this parameter. Instead, use this to establish a baseline and investigate system health if a significant change is observed.

 


 

  1. RTC Power

A ‘real-time clock’ lithium coin battery inside each G2-RAIN allows the logger to maintain time when it is powered down or reset. Values of 2.8V-3.3V are acceptable.

Values that fall below 2.8V indicate the battery is beginning to deplete. At a critical level, the battery will no longer be able to keep time and the G2-RAIN clock will reset to Jan 1st 1970 at 12am (unix timestamp zero) each time power is reset on the system. To avoid data logging interruptions it is recommended a G2-RAIN be sent to NexSens Technology to replace the RTC battery when it hits 2.7V or below.

 


 

  1. Cell Module Current

The total power consumption of the cell module within the system is monitored by the G2-RAIN.

It is best to disregard the status icon designation for this parameter. Instead, use this to establish a baseline and investigate system health if a significant change is observed.

 


 

  1. Internal Temperature

Registers the ambient temperature inside the housing of the G2-RAIN-RTU logger.

 


 

  1. Internal Humidity

Reflects the amount of moisture in the air inside the G2-RAIN-RTU housing.

Acceptable values will range from a slight negative percentage (effectively zero) up to ~40%. If humidity is reported to be greater than 40%, the desiccant bag inside the G2-RAIN should be replaced and the enclosure seal inspected. High humidity can contribute to telemetry problems, and in more extreme cases, damage the logger circuitry.

 


 

  1. Cell Signal Strength

Despite the name, ‘cell signal strength’ is representative of the transmission signal strength for the G2-RAIN.

Expected values are as follows:

  • Cellular Systems
    • -51 to -79dBm for Strong Signal strength (~4-5 bars equivalent)
    • -80 to -89dBm for Moderate Signal strength (2-3 bars equivalent)
    • -90 to -99dBm for Weak Signal strength (1-2 bar equivalent)
    • At -100 or lower connections will be intermittent at best.

 


 

  1. Cell Status

Error codes from a failed or flawed G2-RAIN data transmission attempt will be displayed in the cell status field. Values of zero indicate that no errors were observed.

If status errors appear frequently and data transmissions are affected, contact NexSens Technology and supply the status error code for troubleshooting.
