Description

In order to meet the design requirements, based on the "Outdoor" model, the "DE Panis" configuration is designed.

The name comes from the first installation site of Configuration (School De Panis, TO).

The measuring chain involves the combination of a dust sensor, a composite sensor (T-P-RH), both of third parties, and a remote station made in accordance with the Paradigm.

As measuring instruments have been used to model "Lct 12" Qbit producer with cyclonic filter, and model "8095-N" with solar shield template "00841.6" entambi of Lambrecht manufacturer. The station is the ACROSTATION device family "O" (outdoor) released in 03C release.

In the station it is included Electronic card ACROboard "Station" v02, in its latest release.

This card is dedicated both to the collection function and data transmission (viaGPRS, with internal antenna) that the supply management of energy to the components (and charging the buffer battery).

The power is supplied from the mains, for power supply of the sensor, while the Station houses a buffer battery 12V 12Ah.

Operationally, the station receives the signal from the instrument and generates, with the same continuity, the time series data in native form. The firmware developed for the Configuration allows metadating, time integration, and a first control of accuracy by filtering any unconsistent value. A basic configuration file is pre-installed in the microcontroller onboard the ACROBoard Station.

Finally, the GPRS module, with an unencrypted HTTP protocol, transmits data in accordance with the configuration file ACRONETWORK infrastructure, with the update frequency of the order of minutes Under normal irradiation of the site, the power supply is only guaranteed from solar energy through the supplied panel to the station.

Tips for Mounting and installation

The installation involves the use of a single pole in galvanized iron, preferably Ø 50mm., Which allows the station positioning (containment box) and sensors. The pole can be anchored to an existing structure by means of suitable collars or fixed to a prepared plinth, by means of a cup and bolts structure. Pole, any collars / anchorage brackets and the glass / bolts system are NOT supplied in the corresponding Do-it-yourself KIT.

Download Box

This area includes both the firmware dedicated to this specific Configuration and the basic implementation. You can use the firmware to manage the electronic side of the apparatuses, while the basic implementation is fundamental to run the system (define parameters, position, etc.). You can easily download them or find them in the GitHub repository.

Firmware

The Firmware is the program (sequence of instructions) that has to be integrated directly into the microcontroller placed on the ACROBoard selected for the Configuration. Its main purpose is to start the MIC as well as to interact with the other electronic items. Here you can find the .7z, the .zip folders and the link to the GitHub repository.

Basic Implementation

This set of files is coupled with the firmware and is fundamental to set specific operational parameters (position, frequency of logging, etc.).Here you can find the .7z, the .zip folders and the link to the GitHub repository.
