“…Sedangkan menurut Pamungkas et al (2015) dengan menggunakan sensor BH1750, alat ukur intensitas cahaya tersebut memiliki keakuratan minimal 92%. Dengan menggunakan sensor Lux meter EL7900, Wibawa & Putra (2018) berhasil membuat alat yang sensitivitas yang mendekati hasil lux meter standar (Hioki 3422) dengan nilai kesalahan 0,49%. berbeda dengan penelitian Fakhri (2017) Internet of Things (IoT) memiliki kemampuan layanan tingkat tinggi yang menghubungkan antara benda fisik dan maya melalui jaringan internet (Patel et al 2016).…”

Data intensitas cahaya matahari sangat penting untuk Indonesia yang terletak di garis khatulistiwa. Proyek ini mengembangkan sistem pengamatan intensitas sinar matahari secara real-time menggunakan Internet of Things (IoT), memungkinkan data dapat diakses dengan mudah dari lokasi mana pun. Peralatan ini dibuat menggunakan mikrokontroler NodeMCU dan modul LDR yang dikalibrasi dengan Luxmeter Lx-103. Data ditransmisikan melalui protokol Message Queuing Telemetry Transport, yang menyediakan protokol Quality of Service 1. Uji coba berlangsung di luar ruangan selama 12 jam. Diperoleh data penelitian bahwa regresi linier LDR: y = (-128,14*VADC)+18.621,42 dan R 2 = 0,9693 dengan intensitas cahaya matahari maksimum sebesar 21.451,9 Lux pada jam 9.00 pagi dan kisaran intensitas cahaya rata-rata antara 13.659,26 hingga 20.964,86 Lux Di tengah hari. NodeMCU memproses data LDR dan kemudian menampilkannya di LCD dengan penundaan satu detik. Data diberikan ke server mqtt pada frekuensi 60 detik, dan data terbaru dicatat dalam database SQLite.

“…Made Satriya created the design and manufacture of lux meter digital based on El7900 light sensor in 2018, using El7900 light sensor which has a drawback because the measurement of light intensity of blue filter has a high error. In this study the data was processed by the R8C/13 microcontroller and the researchers chose to display the measurement data on liquid crystal display M1632 [11]. Then the research of luxmeter tools continued by Royditya Astrawinanta titled design build luxmeter equipped with arduino-based distance sensor in 2019, here researchers use MAX44009 sensor which includes light intensity sensor with readings entering the operating lamp criteria 0.045-188.000 lx and distance sensor used hcsr-04 that can read distance well.…”

The lighting of the operating/surgical site depends on the quality of the lighting from the overhead light source and the reflection from the curtain. Light measurement on the operating table is very necessary because it generates light that is irradiated into the cutting wound without dazzling the cutting surface so that pathological conditions can be recognized and must provide depth contrast and anatomical relationships, to ensure this proper calibration method is needed. Long-term use of medical devices can cause changes in accuracy. Therefore, the author makes a tool to measure the intensity of light which is equipped with a distance meter. The purpose of this study was to develop a measuring instrument for measuring the intensity of light in operating lamps, namely a luxmeter by making Luxmeter equipped with a TFT Display Distance Sensor. This tool uses an ultrasonic sensor HC-SR04 to measure the distance between the light source and the sensor module and the MAX44009 sensor to measure the light intensity of the operating lamp displayed on the TFT screen. Based on the module distance setting to the roll meter, the distance error value for the measurement of the Surabaya electromedical engineering workshop lamp at the 75 cm roll meter distance setting is 0.0127% for the 100 cm roll meter distance setting is 0.0045%. The error rate of the light intensity module on the results of the measurement of light intensity on the luxmeter by setting the roll meter distance of 75 cm between the tool and the lamp of the electromedical engineering workshop is getting an error value of 0.082% lux and for the light intensity on the results of the measurement of light intensity on the luxmeter with a roll meter distance setting of 100 cm between the tool and the lamp in the electromedical engineering workshop, that is, the error value of lux is 0.055%. The design of a luxmeter equipped with a proximity sensor can measure the intensity of light and the distance between the tool and the light source and can assist in the learning process with a more effective Luxmeter design that will assist electromedics in testing operating lamps in hospitals to be more efficient.
