Abstract

At present, air quality has been contaminated with vehicle exhaust emissions. This also happens inside the campus due to many students using private vehicles on campus. If not controlled, this condition will get worse and there will be air pollution on campus. This research builds a detection and monitoring device for parameters such as CO, CO2, temperature, and humidity levels. This device was built by ESP microcontroller, DHT22 sensor, MQ-7 sensor, MQ-135 sensor, LCD, buzzer, and Blynk application. Based on the results, the average CO level was 63 ppm. The average CO2 level was 1828 ppm at the parking lots. The average of temperature was 29 ℃. The average humidity was 64%RH. The CO2 level has already worried. It’s caused by many students bringing their private vehicles to the campus at certain times. Pollution occurs at certain hours, especially in the transition time between the afternoon class and the morning class faced each other.
