In both measurement stations the data acquisition is entrusted to a FlexLog model data logger. The FlexLog is a multi-channel logger (the number of channels is chosen based on the sensors), with very low consumption and which can be equipped with a GPRS module for sending data to a remote server. Furthermore, the data is also stored in situ on an SD memory card, which can be removed and read with any PC without any special software.
The logger assigned to the forest station is housed in a Bocchiotti box made of fiberglass and equipped with a key lock. Logger is supplied by a 4.2 V lithium ion battery backed up by a 7 Ah lead acid battery. In addition, the station is equipped with a 5 watt photovoltaic module which recharges the lead battery and thus ensures greater independence for the logger.
The FlexLog associated with the station located on the road is placed in a Bocchiotti box, the same as one in the woods but larger, because it also includes the electronic equipment that manage the alarm signals coming from the on/off contacts, as described later. This box is also equipped with a key lock. The power supply for this system is similar to that described previously, with the difference however that the lead battery is 17 Ah and the photovoltaic module is 40 Watt (this is because the alarm control units must also be powered).
