This study designed a monitoring and control system for the chemical storage room for the maintenance of aircraft cabin components using ESP8266, temperature and humidity sensors, air quality sensors, light sensors, sound sensors and motion detection sensors from human activities and four relays to control electronic devices. using the adafruit website as an interface to monitor the results of sensor detection in the form of sensor indicators and control electronic devices with four switches on

... the dashboard of the adafruit website. The results obtained that the time lag for all sensors in displaying the sensor readings is 31 seconds for the longest time lag and 19 seconds for the fastest time lag, while the time lag for all controls with a stopwatch count is 15,653 seconds for the longest time lag count and 11,050 seconds for the count fastest lag time. Then the calculation of the relay time lag at the time of the operation of the ON switch and the OFF switch is 1.596 seconds for the calculation of the longest time lag and 0.815 for the fastest time lag calculation.
