MQTT based environment monitoring in factories for employee safety

Abstract

Safety of employees, in any industry, especially at the factory level is one of the most important aspects to be considered by businesses. This is of paramount importance, both for the well-being of the employees and that of the corporation as a whole. In factories where working conditions are harsh and employees need to take great caution while going about their work, it is common for mishaps to occur. With numbers going as high as into the thousands it is important that there is a measure of safety for the employees from any possible hazardous situations. As a solution to this problem, we propose a monitoring system to be installed in factories. With this system, we will be able to monitor critical safety parameters of the working environment in these factories so that we are well-aware of the safety situation and the possibility of occurence of any mishap. For the design of this system, we use an ESP8266 Wi-Fi chip enabled microcontroller NodeMCU. To this are connected three sensors — one to monitor temperature and humidity (DHT sensor), an ultrasonic sensor (HC-04) and a smoke sensor(MQ2 sensor). these sensors continually monitor the environment in the workplace and upload the data onto the Losant IoT Platform, which is one of the most powerful cloud platforms which help monitor data by different visualizations and further provisions.
