The main components of this control systems were the NodeMCU 8266 microcontroller and smartphones that communicate using the internet of things (IoT). The system support components include the DHT 11 sensor module as a temperature and humidity sensor, real time clock (RTC) module, liquid crystal display (LCD) as a result viewer, relay board module and pump. The microcontroller read and processed the temperature and humidity sensor output data in the form of a digital voltage signal. The measurement data were displayed on the LCD with an LED indicator and sent to the Telegram application. If the sensor output did not meet the needs of the Chrysanthemum flower, the microcontroller turned on the actuator to turn on the water pump and lights as irradiation. The system test was carried out in the Chrysanthemum Mini Garden by comparing the LCD reading with standard tools. The test results show a difference in temperature of about 0.2-3 oC and humidity of about 1-7%.}, pages = {22--28} url = {https://ejournal.undip.ac.id/index.php/berkala_fisika/article/view/39828} }
