IoT-based electrical energy usage monitoring system in a room in a tropical building

Electrical energy in tropical buildings is used for indoor health and comfort (IHC) purposes, namely maintaining room temperature and humidity (according to standards), lighting (according to standards) and operating equipment to support activities in the room in accordance with the function of the room. To be able to monitor the use of AC electrical energy (for thermal comfort), lamps (for lighting) and equipment in the room according to the function of the room, a measuring instrument is needed according to the group of electrical energy users in the room. This measuring instrument is in the form of a wireless power meter on the electrical panel of the electrical network according to the electricity user load (AC, lights and equipment load), so that the measured electrical quantity (electric current (Ampere), electric voltage (Volts), electric power (Watts), Electrical frequency (Hz), power factor (cos phi) can be transmitted via internet or Wifi media to the energy monitoring dashboard. The Dahsboard is equipped with a measured data base from a wireless power meter so that it can be accessed via the building management's mobile phone to monitor the electrical energy usage of the room and its equipment, so that the cost of electrical energy usage in a room and the amount of carbon emissions produced from each kilo can be known. watt hours of electrical energy used in a building. This is because the majority of electrical energy used in Indonesia comes from coal, diesel and LPG (i.e. energy originating from fossil fuels), so that if it is burned it will emit carbon dioxide (CO2) gas which can cause thinning of the ozone layer, resulting in the phenomenon of global warming. By having an electrical energy monitoring system in rooms in tropical buildings, you will be able to monitor the efficiency of electrical energy use in a room, so you can monitor costs for activities in a room and can monitor carbon dioxide (CO2) gas emissions produced from a room due to the use of electrical energy. (use of electrical energy (kWh) produced from burning fossil fuels and the amount of carbon dioxide gas emissions it produces can be calculated). This IoT-based electrical energy monitoring system is very helpful for building management in carrying out efficient use of electrical energy in tropical buildings which has an impact on reducing carbon dioxide (CO2) gas emissions as well as educating building users to care about preventing global warming caused by gas emissions. carbon dioxide (CO2) which is caused by the use of electrical energy from fossil fuels.
