Environdata’s Weather Recorders

Environdata’s Weather Station Data Recorders are specialised data loggers designed specifically for weather data recording.

Most data loggers are designed for office, laboratory or industrial applications where equipment does not have to withstand weather extremes.  Such equipment is easily accessible and technical staff are readily available to identify and fix problems.

In contrast, Environdata’s Weather Recorders are designed to withstand harsh environments. Moreover, they require minimal maintenance and technical support to facilitate continuous unattended operation over a ten to twenty year lifetime.

Robust Construction

Our recorders are supplied in a fully sealed housing that will withstand even the harshest climate and ensure reliable operation over their lifetime.

Sealed connectors ensure that moisture ingress and corrosion cannot occur.  From our experience, these give better outcomes than cable glands and terminal blocks, which can introduce problems over time.

Electrically, our systems’ digital inputs are inherently more resistant to potential lightning damage than the more delicate analogue inputs that most systems use.

Reliable Long Term Storage

Our weather recorders incorporate accurate time clocks to maintain accurate timing between site visits.

Our system uses multiple memories to provide efficient data storage and to extend the storage time for critical data sets where this is advantageous.

Data and program settings are stored in secure non-volatile flash memory.

Our weather recorders include dedicated automatic watchdog circuitry so that they will restart automatically after nearby lightning disturbances, ensuring minimal or no disruption to data collection and storage.

Easy for On-site Staff

Environdata uses either its own digital sensors or provides an Environdata digital interface for specialised third party sensors for all its weather stations.  This means all sensors have the same easy to use plugin connector and interface.  This simplifies installation, testing and replacement of sensors.

With most of our systems, any communications options required can be integrated into the sealed housing of the weather recorder, simplifying installation and maintenance.

Our systems are delivered fully programmed and calibrated so there is no need for special instruments or testing during the installation process.

Our sensors include an integrated digital signal conditioner that standardises that sensor’s output so that all sensors (of a given model) have the same calibration.  This means sensors are fully inter-changeable, without the need to alter calibration constants in the weather recorder.

Effective Power Management

Our systems are designed to minimise power usage and typically, are solar powered.

Where required, to protect and give preference to the critically important data logging process, our recorders automatically switch off communications systems if the battery voltage is low.

Our sensor power supplies are isolated from our data logging power and each sensor has power isolation from all other sensors and is limited in its maximum power usage. This means that a short circuit failure of one sensor or its cable is very unlikely to compromise the operation of any other sensor, or the system as a whole.

We also include comprehensive battery and solar power monitoring – both voltage and current – to allow the early detection and fault finding of potential power problems.

Accurate Data

Environdata’s digital sensors have a further advantage – their digital signal (pulse rate) varies continuously with the sensing element and this means that the pulse count accumulated over the sample period is a true average of the original signal being sensed.  This ensures that the reading taken is reliably representative of the environment, even with potentially rapidly changing weather parameters, such as wind or sunlight.

Specialised On-board Calculations

Our weather recorders include specialised weather related calculations. This means calculated results are available immediately and alarms can be activated directly without the need for downloading and processing.

Examples of this are Dew Point (from air temperature and relative humidity), Heat Stress Index (for beef cattle), Thermal Work Limit (for OH & S) and Wind Gust and Wind Vector calculations for spray and odour drift.
