Abstract

A green building is a building wherein planning, construction, operation until the maintenance reduces the negative impacts, such as efficient use of energy, water, and other resources, maintaining the excellent quality of the building, and considering the quality of life of occupants. Good environmental damage in the building will affect the health, comfort and, safety of the occupants' lives. Therefore, it takes green buildings concept for buildings where people do activities in a home, an office, a school, a hospital, or a community center. To implement the green building concept, the building needs a monitoring system to monitor the quality of its environment. This research aim is to design sensor systems to monitor the building environment. The parameters monitored are temperature, humidity, illuminance, and noise intensity. The sensor system needs to the integrated with microcontroller and Blynk applications. The sensor system obtains the environment parameter. The accuracy rating for the temperature sensor is 94.41%, the humidity sensor is 93.53%, the light sensor is 91.26%, and the sound sensor is 97.13%. Blynk's warning system can make it easier for users to monitor the environment of a building.

Abstract

Nowadays, fulfilling the needs of human life requires costs. If the daily needs are under control, then the expense spent to meet the daily needs will also be controlled. In everyday electricity usage, the lights may turn on when the user does not need them. This incident resulted in a waste of electricity and costs. This research designs a Light Emitting Diode (LED) light control system using a microcontroller and smartphone application. The features available in the lamp control application consist of Off and On, Timer, Schedule, Electrical Energy Monitoring, and Automation based on Electricity Billing Budgeting. The tools and software used in the design of the lamp control are: Node MCU ESP8266 version 2, SRD-05VDC-SL-C relay module, ACS712 current sensor, Arduino IDE, MIT App Inventor, and ThingSpeak. The time delay from pressing the ON/OFF button on the smartphone until the light turns on is about 1-6 seconds. The error value for calculating the lamp power with the ACS712 current sensor against the lamp power from the specifications on the light box is 1.3%.
