Penelitian ini bertujuan untuk merancang sistem sensor guna memantau lingkungan. Parameter lingkungan yang dipantau adalah suhu, kelembaban, tingkat pencahayaan/iluminasi, kadar gas karbon dioksida, densitas partikel debu, dan tingkat kebisingan. Modul sensor yang digunakan untuk mendeteksi parameter lingkungan tersebut adalah DT-Sense Temperature & Humidity Sensor, DT-Sense Light Sensor, DT-Sense Gas Sensor, Sharp GP2Y1010F46, dan Microphone Sensor Module. Modul sensor ini dihubungkan dengan mikrokontroler WiDo-Open Source IoT Node lalu dikirim secara realtime dan ditampilkan pada serial monitor Arduino IDE (Integrated Development Environment). Setelah dilakukan pengujian dan kalibrasi sensor, DT-Sense Temperature & Humidity Sensor memberikan kelinieran pada rentang 8,80 derajat Celcius sampai dengan 37,90 derajat Celcius dengan R^2 mendekati 1,00 dan error +- 0,30 derajat Celcius untuk pengukuran suhu dan memberikan nilai MAE 0,12%RH untuk pengukuran kelembaban. DT-Sense Light Sensor memberikan kelinieran pada rentang iluminasi 9,00 Lux sampai dengan 3600,00 Lux dengan R^2=9,98x10^-1 dan faktor kalibrasi 0,12x10^-2 V/Lux. Sharp GP2Y1010F46 Optical Dust Sensor memberikan kelinieran dengan R^2=9,99x10^-1 dan sensitivitas 5,91 V/(mg/m^3). Microphone Sensor Module memberikan kelinieran dengan R^2=9,96x10^-1, faktor kalibrasi 3,50 mV/dB, dan MAE 1,46 dB. Terjadi anomali pada DT-Sense Gas Sensor dalam mendeteksi kadar gas karbon dioksida dalam udara.

This research aims to design a system sensor for monitoring building environment. Environmental parameters that are being monitored are temperature, humidity, illuminance, carbon dioxide gas, dust density, and noise. Temperature and humidity are sensed by DT-Sense Temperature & Humidity Sensor based SHT10. Illuminance is sensed by DT-Sense Light Sensor based TEMT6000. Carbon dioxide gas levels are sensed by DT-Sense Gas Sensor based MG-811. Dust density is sensed by Sharp GP2Y1010F46 Optical Dust Sensor and Microphone Sensor Module based KY-038 is used for sensing noise. Sensors connected to WiDo-Open Source IoT Node acts as a microcontroller which sends realtime and is displayed on the serial monitor of Arduino IDE (Integrated Development Environment). The results obtained from testing and calibration of DT-Sense Temperature & Humidity provided a linearity of R^2 get near to 1,00 with range of 8,80 degC until 37,90 degC; a +-0,30 degC error for sensing temperature as well as MAE 0,12%RH for sensing humidity. DT-Sense Light Sensor for sensing illuminance provided a linearity of R^2=9,98x10^-1 ranging from 9,00 Lux until 3600,00 Lux and a calibration factor of 0,12x10^-2 V/Lux. Sharp GP2Y1010F46 Optical Dust Sensor for sensing dust density provided a linearity of R^2=9,99x10-1 and 5,91 V/(mg/m^3) for sensitivity. Microphone Sensor Module for sensing noise provided a linearity of R^2=9,96x10^-1, calibration factor of 3,50 mV/dB, and 1,46 dB for MAE. DT-Sense Gas Sensor used for sensing carbon dioxide showed anomalies in output.
