Abstract

A thermohygrometer is a device used to measure temperature, humidity, and the concentration of medical gases (CO and CO₂) in operating rooms. The temperature in an operating room should be maintained between 19°C and 24°C, and humidity between 45% and 65%, to prevent damage to electronic equipment and corrosion caused by low temperatures and high humidity. Medical gases containing oxygen can also accelerate corrosion. Therefore, a thermohygrometer equipped with medical gas readings is necessary. This study aims to design a thermohygrometer using a DHT22 sensor to measure temperature and humidity and an MQ-135 sensor to detect CO and CO₂ gases. The obtained data is displayed on an I2C LCD screen and sent to the Blynk application via WiFi using an ESP32. Testing shows a temperature reading error of -0.02%, humidity -0.02%, CO gas 0.32%, and CO₂ -0.16%, all within a tolerance limit of ±5%.

Abstract

Augmented Reality is a real illustration depicted through a virtual world explaining the actual situation displayed in the form of video and 3D animation. The advanced features of the smartphone allow using the android operating system. Augmented Reality is relevant as a medium of information, such as information about beat motor spareparts, knowledge about the function of each sparepart and information about the characteristics of damage experienced by motorcycle spareparts. Augmented Reality work system detects objects that have been captured first, this is called a marker. Markerless is an image or involving an object that is detected directly for container that spawns 3D objects in the application. The application design requires Unity software for making AR applications and processing script programs, Vuforia is a database for storing markers. CorelDraw is a graphic design modeling software that is used to make markers. Blender in making 3D objects. Augmented Reality application that is applied to smartphone media using an Android-based operating system. The use of AR applications is expected to be an innovative communication from the workshop to consumers. Consumers also independently analyze and determine what spare parts are being damaged.
