IoT-Based Smart Monitoring System to Ensure Worksite Safety—A Context of Garment Industry in Bangladesh

In this paper, we have proposed and designed a hybrid system that is able to detect fire breakout, gas leakage and noise pollution as well as providing location of the affected area and opening fire extinguish system. Raspberry Pi is integrated with MQ-5 sensor, humidity sensor, flame sensor, sound sensor and camera module. A 360° servo motor is accumulated with camera module to capture affected location even at any angle. To increase the reliability of this system, an authorized person is assigned to assess the real situation. If fire is detected, camera module takes a snapshot of affected region and sends it to admin’s email through 802.11n LAN wireless module. Different sensors’ value also transmits to server through that module in one-minute interval. Moreover, a buzzer is activated in control room when data and picture is sent to admin. If admin confirms the incident, the system will raise the alarm in whole workplace, uncover the water valve of affected region and send message to the owner and nearby fire brigade. Thus, a garment can secure the workplace for its workers.
