It is common for accidents to occur in confined environments, many of these locations may contain in their atmosphere various toxic gases and low oxygen levels, in addition to other hazards.
The intention of this project is to create a product that constantly monitors various parameters, to detect when the worker is experiencing a malaise, or when he suffers some other type of accident, and then alert the supervisors so that they can trigger the rescue and so avoid a serious injury that can lead to death due to lack of medical help.
For this purpose, equipment will be attached to the worker's body, which will read various parameters, which will be explained below, and send them to the station so that it can process the information received and inform everyone nearby if the worker is not well.
Let's go to the hardware: For this equipment that will be with the worker, the following sensors will be used:
- MAX30100, manufactured by MAXIMINTEGRATED
- MPU6050, manufactured by INVENSENSE.TDK
These sensors are read by an ESP32 module that also communicates with the station.
These two sensors read the heart rate, the oxygen saturation in the blood and monitor the amount and speed of movement of the worker's body, to detect a possible fall.
The station has an ESP32 microcontroller, which, upon receiving information on heart rate, blood oxygen level and movement level, will make the appropriate treatment of this information and will then be displayed on a 4.3” intelligent UART display, the data collected during all the time they will be stored in an sd card, which will allow the observation and future analysis of this data if necessary.
