5. Additionally, there is a mode that we have called DEBUG to send the data in JSON format to any HTTP server you want to install. To enable it, using the web browser, go to "Consoles" -> "Manage File system", enable "Show hidden files" and you will see a ".debug" file in the list. Click on the white icon and you will be able to edit it including the information of your HTTP server that will receive the data, the port and a field (1/0) to send or not the data when the light sensor is saturated (0 mpsas).

The photometer takes 6 light measurements at the end of each minute, sending the data. Additionally, it incorporates temperature and humidity information, as well as the raw measurements used for the calculation of mpsas and their calibrated value (calibrated mpsas are displayed on the LCD screen). The device has a built-in generic average adjustment, with which we have obtained an error of about 0.10 mpsas (on moonless nights) in relation to the measurements of a Tess-W. It is possible to perform individual calibrations with parallel FreeDSM / Tess-W measurements, although it is outside the scope of this document. In such cases, the error is reduced to 0.5 mpsas.

In addition to these automatic measurements, the "Read" button on the LCD screen can be selected using the joystick. This will trigger an instant measurement (provided an automatic one is not in progress) by turning off the display for about 6 seconds. |
