  The v-Angra experiment aims to estimate the flux of antineutrino particles
coming out from the Angra II nuclear reactor. Such flux is proportional to the
thermal power released in the fission process and therefore can be used to
infer the quantity of fuel that has been burned during a certain period. To do
so, the v-Angra Collaboration has developed an antineutrino detector and a
complete acquisition system to readout and store the signals generated by its
sensors. The entire detection system has been installed inside a container
laboratory placed beside the dome of the nuclear reactor, in a restricted zone
of the Angra II site. The system is supposed to work standalone for a few years
in order to collect enough data so that the experiment can be validated. The
detector's readout electronics and its environmental conditions are crucial
parts of the experiment and they should work autonomously and be controlled and
monitored remotely. Additionally, threshold configuration is a central issue of
the experiment since antineutrino particles produce low energy signals in the
detector, being necessary to carefully adjust it for all the detector channels
in order to make the system capable of detecting signals as low as those
generated by single photons. To this end, an embedded system was developed and
integrated to the detection apparatus installed in the container at the Angra
II site and is now operational and accessible to the v-Angra Collaboration.
This article aims at describing the proposed embedded system and presenting the
results obtained during its commissioning phase.
