The room temperature depends on the intensity of light. Low light intensity is not proper for the room because it causes bacteria or fungus on the room’s walls. We create a telemonitoring system and air quality control in semi-indoor rooms using wireless sensors as a support system. It can provide real-time information to the user on the screen display. In this study, we use a wireless sensor as monitoring, VEML6070, DHT11, and BH1750 as sensors to determine the air quality in the semi-indoor room. Data will be sent from Arduino Uno to a server through raspberry pi 3 and NRF24L01. Client-server communication techniques are designed for communication between the node and the server, so the data transmission errors can be pressed. The display of the work system will be monitored using a display in the android application. From the experimental results, the system between the node and the server runs well. The experimental results obtained varying Delay with an average delay of 0.318 seconds when there is no change in conditions on the fan and UV lamp. The average Delay is 0.491 seconds when there is a change in conditions on the fan and UV light

Education today demands a better regular and scheduled level of discipline so that the teaching and learning process can take place according to a predetermined schedule. However, most education parties still experience difficulties in demanding this because attendance activities are still manual and less regular in monitoring.The purpose of this study is to assist lecturers in carrying out daily class attendance by utilizing QR Code as a differentiator, which makes it easier for them to use smartphones from each lecturer.In this research, a lecturer attendance application using QR-Code was made where lecturers can do attendance using a smartphone camera for scanning the QR-Code that has been provided in each classroom.From the results of tests carried out on the application made, it was found that the application runs smoothly on several versions of Android and smartphone brands but on Android version 6.0 there is a lack of appearance and when scanning QRCode it takes time. When testing QoS, the highest delay value is in the 2nd Floor AH Building with a value of 120.1695 which means good and the average packet loss is 8%, while for the highest throughput on the 2nd floor AH Building with an average value of 7.598487 which means speed good network.
