This study aims to develop and test an extremely hot weather warning tool. The tool consists of a Node MCU ESP8266 microcontroller, air temperature and relative humidity sensor (DHT22), real time clock module (DS3231), micro-SD-card adapter (HW-125), display screen (2004A), and breadboard-shield. It is connected and controlled by Arduino IDE program. Its measurement ranges for temperature, humidity, and heat index are <10 to >50°C, 0 to 100%, and <27 to >50°C, respectively. This device also presents real-time health impacts by displaying one of five warning levels, namely 1) normal level (HI < 27°C), 2) caution level (HI 27°C to <32°C), 3) extreme caution level (HI 32°C to <41°C), 4) danger level (HI 41°C to <54°C), and 5) extreme danger level (HI ≥ 54°C). The data can be directly transferred to a computer by a card adapter. Based on validation with the occupational health and safety standards instrument, no outliers or missing data were found. HIEHT had a highly positive correlation with HIQT36 (r=0.99; p<0.01; n=4,182). Heat Index data measured by this tool was found to have acceptable values with a bias of 0.54 and RMSE of 0.99. For the pilot areas tested, it was found that the extremely hot weather warning tool can fully measure and record, as well as continuously display the results according to the tested date and time. These results show that the developed tool is a simple, easy-to-use, inexpensive, tiny, and portable instrument that can be used to monitor and measure heat to widely communicate extremely hot weather warning information to vulnerable groups and the general public in the community.

The increasing population level of society makes the level of public consumption of natural resources also increase, in this case the increase occurs in the use of LPG (Liquefied Petroleum Gas) fuel. With the increasing use of LPG fuel, it is possible for fires to occur caused by LPG gas leaks. However, not all LPG gas cylinder providers provide additional safety systems on the LPG cylinders they sell. So an LPG gas leak detection device and a system that can provide information in the event of an LPG cylinder leak are needed. For this reason, an LPG gas leak detection device is made using a Telegram notification system, and an MQ-2 Sensor that can detect LPG gas and provide an alarm sound and LED indicator and LCD display display. so that it can provide a warning if the owner of the LPG cylinder is outside the house. All of these components are controlled using a Nodemcu Microcontroller. This tool has the advantage of being easy to use and compatible with all Telegram-based communication devices.

The integration of automation in the printing industry has revolutionized processes, yet manual calculations persist in centers like Aslaka, managed by Electrical Engineering Laboratory Assistants, leading to inaccuracies and opacity in pricing. This study aims to address this gap by developing an automated pricing device, ensuring precision and transparency in paper quantity and total cost determination. Utilizing research and development methodology, comprehensive testing of IR sensors and IoT-based data transmission was conducted to guarantee reliability. Findings demonstrate successful paper detection by IR sensors at 2 cm and 3 cm distances, with sensor readings accurately displayed on a 20x4 I2C LCD screen. Data transmission to Google Sheets via Pushingbox API exhibited exceptional accuracy, achieving consistent 100% matching. This innovation enhances efficiency and transparency in pricing, offering significant implications for the printing industry's advancement. Highlight: Development Method: Utilizes research and development for comprehensive testing and reliability. Sensor Precision: IR sensors accurately detect paper at varying distances. Data Transmission: IoT enables seamless data transfer to Google Sheets. Keywoard: Automation, Printing Industry, IR Sensors, Transparent Pricing, IoT
