“…The RTC set the clock, and the Dfplayer played the "Adzan", a sound file stored in the memory card. The LCD on the microcontroller [22], [28]- [30] displays the words "it is time for prayer," and the speaker says them aloud. The microcontroller then instructs the Ethernet shield to send it to the server and the telegram [31][32].…”

The development of science and technology has been increasing rapidly, providing convenience in everyday life. Various household appliances and office work tools use electronic devices to ease the works, including bell warning systems for prayer times. The system notifies the people when the times for prayer comes. The warning systems used presently have not operated automatically. The research aimed to design and implement a series of automatic warning bell system for prayer times, that sent a notification to the telegram. It used Arduino Mega 2560 as the data processor. The result found that the tool, equipped with an RTC, a Dfplayer, a loud-speaker, and an Ethernet Shield, worked satisfactorily by sending a notification to the Telegram.

A Graphical User Interface (GUI) design was developed to extract data from a data logger. The low-cost data logger was developed using a common pic18f4550 microcontroller. Simple data recording feature is implemented by using the Electrically Erasable Programmable Read-Only Memory (EEPROM) module from the microcontroller unit. The GUI software employed VB.net 2013 and has been tested to work in window 10 environment. Simulation work was performed with temperature and humidity sensors using Proteus VSM software. Upon simulation, the GUI shows its capability of extracting measured data from the data logger and converting the data to a Comma-Separated Values, (CSV) format for further analysis.

“…The sensor used is TEMT6000 which results in simulations of only up to 10,000 lux, in this study the processor is ATMEGA 8 and researchers chose to display the measurement results on liquid crystal display 2 ×8 [18] Then a lux meter made by Akhmad Akhsin Nasrudin. namely the design and build of flux meter BH1750 application as a microcontroller-based water turbidity measurement tool in 2015 [19], but still has a weakness in the measured value due to the limitations of the design tool related to the measurement of water turbidity and is influenced by poor measurement techniques so that the maximum error value is obtained at 6.35%, in this study the data was processed by ATMEGA 328P and the researchers chose to display the measurement data on a 2×16 liquid crystal display [20]. Herlia Agni made an Arduino Uno-based lux meter tool equipped with a distance meter in 2017, using the GY-302 type BH1750FVI light sensor which has a drawback because the light intensity measurement is only up to 31562 lux in his research.…”

The measurement of the operating lamp light on the operating table is very necessary so that the light rays do not glare during surgery and pathological conditions can be recognized easily without any shadows. This study aims to design a tool to measure light intensity equipped with automatic distance measurement. The design of 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. The design of the tool has been tested on operating lamps. In this study, measurements were made on two light sources, namely the GEA brand operating lamp in the Operating Room RSIA Putri Surabaya and lamps in an Electromedical Engineering Workshop on the Surabaya campus. The results of measurements when using a lamp in an electromedical engineering workshop in Surabaya with the distance between the module and the light source using a 75 cm roll meter, it is known that the error value is 0.0127% for a distance of 100 cm as much as 0.0045%. The module error value when measuring the intensity of light between the tool and the lamp in the electromedical engineering workshop with a roll meter distance setting of 75 cm gets an error value of 0.082% lux and at a roll meter distance of 100 cm, the lux error value is 0.055%. The design of a lux meter that is equipped with a proximity sensor can measure the intensity of light and the distance between the device and the light source and can assist in the learning process with a more effective Luxmeter design that will help Electromedical Technician in testing operating lamps in hospitals become more efficient
