This paper offers the BLE 5.0 wireless technology and the Internet of Things(IoT) sensor node, which aims to monitor destructive environmental circumstances for safety applications. The proposed low-powered sensor node supports multiple environmental sensors. Sensor data is sent to mobile and to cloud server using BLE 5.0 based gateway.We focus mainly on the monitoring of ultraviolet, carbon dioxide, carbon monoxide and few environmental constraints. Bad environmental eminence can root serious health complications to peoples. Therefore, the neighboring environmental information is collected in real time by the wearable node and conveyed to distant cloud server. The information is then showed to approved handlers via web-based application on the cloud server, and when an emergency occurs, the device notifies the user via the mobile application. Experimental outcomes show that our safety monitoring system can operate consistently with less power consumption.
