Project Description

Green energy monitor – live data

by dutuc.nicolae


The project of this posting is designed to monitor the production of green energy in real time.
The module reads the values of the analog inputs which are connected current sensors (one for photovoltaic panels and a wind turbine), the sensor voltage (for bench batteries) and a digital input for temperature sensors (for temperature measurement bench batteries and environment outside), web server transmits (POST method) and call a PHP script that inserts data into a database.In this way data can be recorded for years.
