The most required sensors for the BlueLog meteorological station are as follows:

PV pyranometer, with Modbus RTU Output, is constructed from a monocrystalline solar cell connected to a high-precision shunt. This irradiance sensor must be placed away from any kind of obstacles, and it contains an integrated module temperature.

Ambient temperature Sensor, with Digital Output, is mounted inside a solar radiation shield which has 6 aspiration plaques allowing air to pass freely. In fact, this shield is used to protect the ambient temperature sensor from any kind of irradiation.

Module temperature sensor, is covered by an aluminum plate to protect the data obtained. This sensor is used to measure panel temperature values in (° C). In addition, it offers an economical solution for solar power plants and universal applications.

Wind speed sensor, with Digital output is made of stainless steel. It is used to measure wind speed in solar power plants, and to provide the data to the Bluelog.

Wind Direction sensor, with Analog output and made of an UV Resistant plastic material, is usually used to measure or report the direction from which the wind blows.



The BlueLog is a programmable device that records individual values and series of measurements over a long period of time. It collects all relevant data for the monitoring of the solar system. This Datalogger also offers a wide range of interfaces and functions for the control of PV systems.

The virtual control room or VCOM is a monitoring system for photovoltaic installations. It allows to quickly locate malfunctions in case of failure and to eliminate them efficiently. As it graphically shows the performance report and the thermal map. In addition, it compares the actual and theoretical production. VCOM allows mobile monitoring via iPhone and Android application.

VCOM Monitoring System

Thanks to the graphical user interface, the Datalogger can be quickly and simply configured locally or remotely via VCOM.


During installation, if you face any difficulties, SEVEN engineers are available to provide you with a remote setup service and information on anything you may need.

Our sensors are produced in our plant operating in the Organized Industrial Zone of Corum. We have local and international sales.
