Abstract

NodeMCU ESP8266-based automatic clothesline system using dht 11 and ldr sensors is designed to optimize the drying process with automatic control. The system is also equipped with a telegram-based notification to provide real time information to users with time, temperature, and light intensity parameters. The test results show that the system is able to move the drying rack automatically based on the condition that the drying rack will automatically exit when the temperature is >30°C and the LDR value is <100 (bright light) at 08:00, and the drying rack enters when the temperature is <30°C or the LDR value is >100 (dim light) at 16:00. In addition, the system is able to detect rainy conditions with temperature parameters <30°C and LDR value <100 between 08:00 and 16:00, although these conditions did not occur during the test. The limit switch is used to ensure the movement of the clothes rack to stop at a predetermined position, and the motor response test shows that the motor does not stop immediately when the limit switch is active due to the delay of network quality influence, but still in accordance with the system logic.
