Abstract
Abstract: In the present-day world, air pollution has gained huge attention and eventually become a major threat to society. Considering the exigency and magnitude of air pollution, this paper focus mainly on the device which is capable of monitoring the air quality, vibration levels of the ground, and a type of fire safety alert system for the employees working in the industrial environment. This is implemented using a WIFI-enabled ESP8266 NodeMCU microcontroller which is interfaced with air quality monitoring sensors MQ135, DHT11 (Humidity and Temperature) sensor, Geophone sensor to detect measurements of vibration levels in industries, and a flame sensor to prevent the workers from fire accidents. The buzzer is used as an alert module. The sensor data is stored in NodeMCU and the data is analyzed and stored in the cloud platform and monitored on the BLYNK (an IoT platform) by interfacing the app with NodeMCU.
