Abstract

At the beginning of 2020, the world was shocked by the emergence of a new virus, Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-nCoV- 2) and the name of the disease is Coronavirus Disease 2019 (COVID-19). Common symptoms of COVID-19 are acute respiratory distress, fever, cough and shortness of breath. One of the efforts to overcome the transmission of COVID-19 is by sterilizing the room. This research designs an automatic room sterilization device using UV-C lamps that can be controlled using the Blynk application. There are 2 working principles of this tool, namely automatic, the lamp will turn on according to a predetermined setpoint and manual, the lamp will turn on manually like a normal lamp. Hardware used to make this tool are NodeMCU ESP8266, DHT11 sensor, PIR sensor, UV-C lamp, and Relay. As for the software used are Arduino IDE and Blynk Application. This research has 3 tests, the first is testing the lamp automation system where the UV-C lamp response is in accordance with the notification in the Blynk application. The second test is a human detection system with a PIR sensor where the sensor can detect with a maximum radius of 5m. The third test of room temperature monitoring system with DHT11 sensor with digital thermometer comparison tool. The average error value is 0.88% with the accuracy of the DHT11 sensor of 99.12%

Abstract

The Dendrobium orchid (Dendrobium spp.) is widely appreciated for its beauty and durability in the horticultural industry. To ensure optimal growth, continuous monitoring of environmental conditions is essential. This research presents an Internet of Things (IoT)-based monitoring system that observes real-time temperature, humidity, and soil moisture levels around the orchid. The system utilizes a DHT22 sensor for measuring air temperature and humidity and a soil moisture sensor for detecting the moisture content of the growing medium. An ESP32 microcontroller processes the sensor data and transmits it to the Ubidots cloud platform for real-time visualization. Testing showed that the sensor system achieved an accuracy rate of 4%. Data consistency between the serial monitors and the cloud was maintained, except when network disruptions occurred. This system allows users to remotely monitor critical parameters necessary for orchid health, facilitating better decision-making and timely intervention, ultimately improving the effectiveness of orchid care and maintenance.
